It works and its plug and play!!! Based on some news that a guy on the Miata board had been successful in using the PIE Alpine CD Changer adapter with an Alpine M-Bus RCA input adpater I thought I would risk the $80 and give it a shot.

There is a post on this board with a quote from a PIE representative claiming the CD Changer adapter would not work in this manner, this does not look to be the case.

The CD button now allows you to switch between the single in dash CD player and what it thinks is an "external" cd changer, in this mode the display flashes EX 1. In my case I used a Rio S35S for the test. Works fine, quality is great, I have no ground loop noise as some reported on the Miata board while using an iPod mini with the same adaptor.

See pics below.

Parts:

Alpine MAZ/PC - ALP, CD Change adapter $76.99, www.pie.net, no Alpine CD changer is required to make this work, although you could add alpine's 6 Disc CD/MP3 player for $260 if wanted.

Alpine M-BUS Input Apapter $19.99, connects to the MAZ/PC via M-Bus and gives you RCA inputs. $19.99

Total Cost: $96

Install, 25 minutes:
Remove shift knob, center console, cigarette lighter tray, 2 screws under the AC controls, security bolt on drivers side of radio, gently pull the radio out while using some small screw drivers for leverage, remove AC harness, remove main radio harness.

Grounding and Line Noise:
I have not had any issues yet, but I have also not run my MP3 player off car power. A Ground Loop Isolator may be required in some cases or grounding the line-in would also work as the PIE connector does not use the ground pins on the J-02 connector (16 pin connector).

As per MazdaRadioDoc, to check your head unit's software code: Power the radio on, then press and hold the text and preset 1 buttons at the same time (you might need to start pressing the text button slightly before the preset 1 button). The Software version should be in the display. '04 vers. 9.40/9.50/9.53/9.55, and '05 ver. 9.67 (poss. SAT compatible).

"EX-1" may still blink, even though the aux input is working.

Great post, people have tried all manner of ways to get something similar going, this one is pretty simple to do.

Fantastic news.

I don't understan how can I install it and which Mazda components I need.
Can I install an Ipod on rx-8 with nav system and multi cd changer (6cds)
Thanks

www.pie.com is wrong

http://www.pie.net/pcmazda.htm

Can I install an Ipod on rx-8 with nav system and multi cd changer (6cds) and use them?
I see only a bus (1 imput and 1 output) on the product

Is there a player that read either 6cds than mp3 cd.
Where Can I find it?
Work with this adaptor?

My RX8 has nav, no oem mazda cd changer though. The part I am describing is an aftermarket converter which is meant to allow the use of an external Alpine CD Changer. As long as the 16 pin port on the back of radio is free you should be all set.

The oem mazda cd changer does not read mp3s. This adapter would allow you to use an Alpine CD changer which can play MP3 CDs.

I am going to give this a shot. I have been waiting for too long for a solution. I hope this wasn't something unique about your setup. Fingers crossed. Its only money.

lets see how this works out.. ill have to jump on it afta my vegas trip perhaps this and an iPOd will do me fine for now.. as i slowly work on my carputer..

Which Alpine model read mp3 and multy cd?

I can't find any company that sells this gear that is willing to ship internationally. Dead annoying.

I see that CHA-S634 is an mp3 multi cd player.
It has Ai-NET connector. Can I use with MAZ/PC - ALP?

I see also the original product KCA-130B Cavo Adattatore MiniBus per CD Changer MP3 (CHA-S634). This transform Ai-Net connector to Mbus connector (13Euro).

So whith Alpine CHA-S634 + Alpine KCA-130B = about xxx+15Euro =xxxEuro I'm installing mp3 multi player on my rx-8 and I could control the cd player from the radio.

Is it right? Why should I buy MAZ/PC - ALP?
Thanks

You have the right parts and idea there. The CD Changer you note is Ai-Net only, thus it needs to be converted to M-Bus.

Without the MAZ/PC adpater you would have no way of hooking the Alpine CD changer to the stereo. The MAZ/PC adapter is MBUS only, thus the need for the converter.

CHA-S634 (Multi cd changer with mp3) + Alpine KCA-130B (is the converter from Ai-Net to M-Bus)
Now cannot connect this Mbus connector directly to my rx-8?

How? There is no MBUS connector on the Mazda stereo. That's why they make an adapter.

My question...what exactly will this allow you to do? For iPods or whatever its just an aux in, no way to control the iPod other than via the iPod itself...unless there is an MBus-to-iPod interface somewhere? For its intended use, i.e. hooking up an Alpine changer...I'm guessing you can control the changer from the head unit/steering wheel. Does it have the ability to display ID3 tags like the stock MP3 playet? I'm betting no, unfortunately.

jds

Sounds like this is the magic bullet for all of us trying to run aux-in to the head unit.

Sweet action

Hazaaaaa. Found a UK supplier. Mines on it's way.

the site is www.pie.net

thank you thank you
could you post a link to the miata msgs since I couldn't find them. I may want to see how they are dealing with the noise issue.
Have the parts. Bought them a couple of months ago, but when the PIE folks claimed it wouldn't work, I never tried it. hehehehe I know what I am doing on Saturday!
whoopeee!
thanks again!
my ipod thanks you too!

BritSti,

Could you please be so kind as to list the part numbers and possibly the exact URLs you used to purchase the MAZ/PC - ALP adapter as well as the M-Bus to RCA adaptor?

I browsed around www.pie.net and I was able to locate the MAZ/PC adaptor but not at the price you listed. I haven't been able to find the MBUS to RCA adaptor you referred to. I just want to make sure I get the right parts.

Sorry if I've missed something. I know what parts you're referring to because I've seen similar products. I'd just feel much better buying the exact ones you've bought because we know the combination works (and you also seem to have gotten a decent price on them).

Regards,

Can someone save me the time of pulling my car apart? I am wondering if the Bose Stereo with cd changer (no nav) has this 16 pin plug on the back? Can anyone verify this for me?

This is a huge find IMHO!! Best of luck to everyone that can take advantage!

-RX8J

BOSE with no nav has it.

Does the Bose with the changer have it? (or maybe both with and without is what you meant??)

Sorry for the misunderstanding ... I am still not clear

-RX8J

Somone correct me if I'm wrong, but it should be available on all versions of the head unit in any RX8.

You can see the exact port we're talking about in this thread (http://www.rx8club.com/showthread.php?s=&threadid=16279&highlight=hacked).

I think I think I think - but not 100% sure - that the Bose w/changer already uses that connection for the changer.
Most descriptions of the part tell you that you can not use this with a CD changer hooked up.
The pie people would know.
Someone should do a search and either link to, or bump up the original thread about the stuff where someone originally descrivbed all this stuff. I believe the people from Logjam were the ones who claimed it didn't work? Dunno.

Here's the info on what I got/paid:

Logjam (http://store.yahoo.com/logjam/ )
part mazpcalp 79.95
shipping 7.50
(15% restocking fee for returns !)

http://store.yahoo.com/logjam/piemazpcalp.html

The RCA adaptor can be found here for 14.95
http://www.pricescan.com/itemsx/item280449.asp
Logjam chages something like 30 for the same thing.

I will know probably on Saturday how well this all works. I'll post if I get it hooked up.
Sue

The PIE people told the person on the Miata board that it wouldnt work at all and that seems to not be the case, so I wouldnt trust them to know about it working with a changer in a car they dont support.

I do have a stock Bose changer and I will pull the radio to check if I have to, but I think there is probably someone out there that has had theirs out and can tell me/us if the 16 pin socket in question is being used.

If nobody has done it and it will help us out, I can pull the radio over the weekend and check..... Again, hopefully i dont have to, but I will if needed (and post the results of course).

The 6-disc changer option in the RX8 is an internal module. The changer connects internally. The port we are referring to is a 16-pin external port. The two do not interfere with each other.

The port is not used for anything that we know of yet, with the possiblity of a TV Tuner option that is supposed to be available at some point in the future in Japan. There is also talk of a Sirius radio option that may be released sometime this year that would also use that port. But so far, I am not aware of any hardware on the market today that consumes that port. And I believe it is available on all head units in all models of RX8.

Thank you very much BritSti for posting those direct links and for taking the time and making the effort to test this all out.

Please post pics of where all of you are storing your players to keep them out of the way. Can't just have wires draped all over your interior, can you?

This is great news. Can it be too good to be true for those of us waiting for Overloads aux in?

A blind guy here in electronics so help would be greatly appreciated:

a) What the heck is a protocol converter

b) What the heck is a DPX?

I have a Mazda 3 which should be the same head unit as the RX8 and others. What exactly parts should I buy.

I have a cassete unit to use with my IPOD, do I need to disconnect it?

The posting is great, gives us Ipod owners hope that finally we can do something good but if you're not used to do those things - as myself - you're lost. Who would be the good soul that will post a step by step with a item list for the rest of us?

Anyway a great post and we should thank all that went for it. Keep the replies coming.

Cheers all

Hmm... anyone try attaching one of these to the the aforementioned Mazda to Alpine M-BUS adapter?

http://densionusa.com/merchant/merchant.mvc?Screen=PROD&Store_Code=DU&Product_Code=I11_MBUS&Category_Code=IA_AFTERMARKET

Seems like an expensive route, though

--SL01

I had looked at that, may take the plunge and try it out, but with a Mazda IceLink kit in the plans not sure if it's worth sinking the $79 on the adapter and another $159 for the Alpine MBus IceLink.

Although buying a good mount and Belkin Power cable for a iPOD mini would cost maybe $60, so that makes the IceLink a $100 addition.

The Dension forecast pricing is $219 for the Mazda kit on their site so the net total would not be that different if you tried this now.
http://densionusa.com/merchant/merchant.mvc?Screen=CTGY&Category_Code=F

I would be somewhat worried about ground noise also, as the PIE MAZ/PC-ALP adapter isn't grounded for the audio line input which it would receive from the IceLink Mbus setup. I have seen some reports of ground loop noise with IceLink setups in the ipodlounge.com forum.

I found your post from a thread from Mazda6club.com. I'm very interested to see if this will work with the Mazda6 since it uses the same head unit as the RX-8/Mazda3. Hopefully this will work out! I can finally bring my iPod in the car with me instead of burning 100s of CDs and constantly swapping them out.

THANKS!:D

Happy Monkey,
When excentric first brought up this port, and we didn't know any better the PIE folks (or one of their distributors) posted that this (connector/translator to m-bus to rca) would not work. Obviously they were wrong.
That being said, another thing that came up and no one ever did figure out is that on this page
http://www.discountcarstereo.com/datail.aspx?ID=445
they state clearly NOT COMPATIBLE WITH MAZDA6.
The folks at discount car stereo have updated the page to include the use of the adaptor with ipod etc, but they have NOT removed the Mazda6 incompatibility warning. But if you think it makes no sense, since the 8 and the 6 have essentially the same head unit, I agree. But be aware before you take the plunge...

A- a protocol convertor connects to the back of your radio and "translates" the elctronic signals from the "language" of the mazda radio to the "language" of Alpine.

B- I believe DPX is a proprietary name given to the translator by the PIE makers

the SIMPLEST set-up requires 2 parts, plus whatever your individual iPod or device require to hook into any ordinary audio device.

1- MAZ/PC-ALP : this will connect directly to the back of your radio and give you an m-bus connection with the Alpine "language".

2- ALP/M-RCA : this will attach to the m-bus connection above and give you standard RCA input jacks.

Your ipod/ other device should have an RCA out connection, whether it comes from a dock or output jacks. Wherever the signal is coming from, you will need to make sure that there is a wire that ends with 2 MALE RCA type plugs (red and white ususally). This will hook directly to the RCA input jacks.

Other , more direct options will be coming available (like the ice-link mentioned above) over time. You may or may not wnat to wait for a more simple approach to become available!

edited to inclue : no I don't think you will have to unhook your tape player.

Thanks brit! I finally have an aux in for my XM and other stuff! I'm gonna order this stuff right now!

Awesome!

Ok guys BAD NEWS!! I got the two pieces as mentioned in this thread hooked them up and the audio worked for about 60 seconds then my Nav Display "switched" to TV Mode (Really weird screen with Japanese lettering on it!) and the audio went out. If I hit the CD button again it goes back and works, but the same thing happens every 60 seconds! I called PIE and they said this set up would not work the way we are trying to use it. My guess is the adapter is not sending the proper signal to the Head Unit that a cd is in the changer and playing. When it does play my RED led display says "EX 1" with the 1 blinking as if it is looking for CD 1 and can't find it. Anyone think they could hack this? Any help would be appreciated.

I got mine today and won't be installing for awhile since I am waiting for some other stuff and don't want to tear the center console apart more often than necessary. Now we have one "IT WORKS!!!" post and one "BAD NEWS" post. Anyone else install yet?

I installed mine today... GOOD NEWS! The sound quality is GREAT! BAD NEWS... it doesnt work for NAV cars. The EX 1 keeps flashing, and after about 15 seconds, it changes the screen to a TV Screen with a bunch of Japanese symbols... Sooo... I guess im just gonna go back to the FM Modulator, and wait for the AUX IN module... If anyone wants to make me an offer on the two pieces, the input adapter or the MAZPC converter... let me know, looks like it will work great for non Nav System cars...

How do you know that it will work with cars w/o NAV?

Damn. I am one with flyboyindy. I bought. I have Nav. So it won't work. I guess.

The sound portion works just fine. The problem is that the port on the Nav System cars is somehow connected to the screen. So for me to watch movies, it kills the screen but keeps the sound going. It will work great for an ipod or another mp3 player...

Okay. Now I am confused. If you connect the PIE connectors (which I got today but haven't unpacked based on what I read) it works as an audio input for an mp3 player but not for a video feed? Is that what you are saying flyboyindy? So for those using it only as an mp3 input it will work fine? but at a cost of not being able to use the nav system while listening to your mp3 player?

Ok, let me start from the beginning.... I plugged my PIE unit into the back of my stereo. Then i plugged it into my source, the AVElectronics unit. I hit the CD button, and it worked great for about 15 seconds... then the screen on my NAV unit changed to a "TV 1" Screen...looks like the JDM TV unit screen because it had a look similar to the the NAV software. The audio still worked, but it wouldnt hold the video feed. I dont see how it would cause any problems if you were just using it as an audio feed without the use of the screen...

When I setup mine. The NAV display went into the JDM TV mode and the audio went out. So nothing would work. If you press the CD button the audio would come back for the 15 secs or so then cut out again. I talked to the tech support guy at PIE and he said this setup will not work for us as AUX in! It WILL work if you plug in one of the alpine CD Changers but that still doesn't solve the problem of getting an AUX in.

On another note maybe Overload is reading this (Hopefully)!

The problem that I see with this unit is that by using the AUX in connecter on the M-Bus there is no signal telling the head unit that there is a CD in the changer (because there is no cd changer). I bet Overload could figure out how to fake that signal through these connectors. so we could use it. I for one am willing to loan my unit for this purpose if he could figure it and send me back a working unit.

What do you think overload?

Played with the setup a bit more myself as I do have nav also. Basically mine works with no cutout etc while my nav display is closed, which is most of the time for me, great investment on my part.

Opening up the display creates a nav video display cutout after 30+ seconds, audio remains. It seems like people with nav are getting a few different results.

My nav "software" was recently upgraded after disappearing, the different sftwr revs may account for something.

Discount car stereo have added a note that this can be used as an aux-in solution on their site.

S

is there anybody without NAV that has tried this? What is your results?

I have no nav, but CD changer...just ordered mine, and can't wait to hook up my XM to it...i am also working on a switch, so i can leave the XM hooked up, but also hook up something else, and by throwing the switch decide what i want to listen to. I will keep everyone posted...

No go for me too. I have Bose System and No Nav. Audio works for 15 secs or so while the display flashes EX1 and then the system turns off.
Same results for my XM radio and iPod.

Well isnt that a pile of poo! I was thinking of using this for my carpc install. Looks like ill have to find another way to get the audio...

I have the Bose system that comes with the Touring Package, and I also have the 6-CD changer. Does anyone know if a PIE solution is compatible with the Bose system when it's equipped with the 6-disk changer? That may be the component that's necessary.

I too have a Bose with Changer (No NAV). It seems that we are out of luck. As far as I can tell it only sounds like it works for a NAV system (although you cant have the NAV screen open or the display goes blank -- But the audio works).

If anyone can figure out a way to get a Bose with Changer and NO NAV to work PLEASE post. There are a lot of us waiting for a solution (but at this point is doesn't sound good).

-RX8J

Here's my report. I have a Bose radio/cd player - no changer and no Nav.

I finished! It works for me and it works great! I hooked the blue connector from the PIE adaptor to the back of the unit (on the driver's side). I then ran the RCA end down the back and under the ashtray assembly. I hooked up an RCA to miniplug cord there and ran that along the side of the inside of the shifter/emergency brake area, and then out into the cup holder area by exiting through the small opening by the emergency brake. I then plugged the miniplu into the earbud jack, and turned the system on. WIth or without a CD in the CD drive, if I press CD it will switch back and forth between the two.

Main problems I had: finding the side bolt to remove the radio assembly (after I found the TSB about fiinding the bolt I got it.)

FIrst go round it did not work - found out that the PIE adaptor has to really plug in all the way - I hadn't been shoving it on the at the Ppin connector as much as I should have.

No ground noise, it keeps working on EX just fine, with the - 1 flashing. I ran it about 10 minutes with no problems.

Suggestion for people who are having the problem of it switching off EX-1 - try setting your iPod volume up high, in case it needs a minimum signal to "see" it.

affenage,

Good job! Would mind pointing me to "the TSB about finding the bolt"? I can tell I'm going to need it, but my 8 is only two days old and I'm learning my way around this forum.

I had a TransPod for my 2G iPod, hacked to use a cassette adapter instead of its iffy transmitter: http://www.eldoradosoft.com/transPod.htm

I lost use of the TransPod when I got my 3G iPod, but there's now a new 3G TransPod at http://www.everythingipod.com and I assume it will be equally hackable. This time, though, I'll be able to use the PIE for direct input!

The TransPod is a super mounting device when hacked for better audio. It's easily controlled while your hand is on or near the shifter, and reasonably visible so your eyes don't have to wander as far.

Here are the DIY directions with pictures for removing the head unit.

I used a (I forget the name they remove bolts) with an extender on it - you go in from the driver's foot well area on the side of the unit. I ended up not putting it back for now because it was so damn annoying to get out!
here's another thread about it
http://www.rx8club.com/showthread.php?s=&threadid=30625&highlight=side+and+bolt+and+head+and+unit

good luck... I wish this would work for everyone, I know how badly I wanted something like this - at least until overload gets his fancy one finished.
Sue

Those who have gotten this to work with the RCA plugs, where are you mounting them? Did you do do some cutting into the dash or some other place not noticeable?

i plan on putting mine in the plastic insert i am making for my ashtray slot...i have my xm commander in there now, and i am working on a plastic insert with a switch and two rca plugs so i can use either my XM or my MP3 player with the aux in...i will post pics when it is complete

I suppose you guys could get this unit and all you iPod owner out there could then get an ICElink for the M-bus, it's 159 last time I checked, I personally am just going to wait for the RX-8 model of the ICElink, since the Apple created integration is just a meaningless hack anyway and it's sub-par compared to the ICElink which is rather sad, it seems as though apple rushed into this not fully thinking about it, but it's an idea for you guys who just can't wait

Thanks for the DIY info, Sue.

I bought a 3G TransPod yesterday, and found it has an "Aux Out" jack already built into it. I just have it on its mounting stick plugged into the lighter, but it's pretty stable even so. I haven't figured out where to do the permanent mount, and I'm really not happy about drilling into the brand-new dashboard... but I do like the utility of the TransPod.

In another thread I saw someone mention high-freq noise from the car's ignition. I hear this with the TransPod, and heard it with the 2G TransPod (hard-wired) as well. I'm concerned about the noise isolation of the TransPod and will be experimenting with it.

Randy

Hi Randy -
I bought the Belkin power adaptor for the car. I looked at the Transpods - and I saw that they make an Aux out one now, but I decided to wait on it, since I don't know what my final hookup will end up being. Ideally I would like a more permanent solution like the Transpod, but for now I am content to hook up the two wires and leave the iPod on the center console or in the cup holder.
If eventually I have a hookup that will allow me to read the text on the dash and control the stop/next song/etc with the radio controls, then I will probably mount the whole system in the covered compartment behind the cup holder.
I don't have any noise at all - you might see if hooking it up through the earbud jack vs the aux out on the Transpod makes a difference - it may tell you where the source of the problem is. I was a little hesitant to add the power line, after early reports of the high frequency feedback, but as I said, mine has been smooth sailing so far.
good luck!

I appreciate everyone’s attempt to tackle the issue of not having AUX-IN source(s) on the RX8. However, the more explanations I see, the more it seems people are being confused. So, in an attempt to provide some clarity, it appears that there are 4 basic configurations out there that we are all trying to address with the P.I.E. + M-Bus add-ons:

1) CD Changer – No Nav. Does this work?
2) CD Changer – Nav. Does this work?
3) Single CD – No Nav. Does this work?
4) Single CD – Nav. Does this work?

Can anybody who has made these attempts please confirm or deny that the P.I.E solution will or will not work. And please specify which configuration (above) you have.

Thanks to everyone in advance.

#3 single cd - no nav (and it is Bose)
iPod mini connected through headphone jack

works

ymmv

Sue

Option #3 DID NOT work for me. (Single CD Bose system.)
I was attempting to connect either a 2nd generation iPod or an XM Commander. Neither worked - just 15 seconds of audio before shutting off.
It may be helpful to also list what audio source works as I suspect it may have something to do with the strength of the signal received instead of the combination of audio components.

Option #2

2) CD Changer – Nav. Does this work?

DOES NOT WORK!

I have it and I have talked to the Tech Guys at PIE.

So ask your buddies at PIE why mine works. Mention I bought the adaptor in early April. I bet they aren't allowed to sell a version that can do this, and the newer ones are disabled.
just a hunch.

I have finally had the time to play around with this some more.

My car OPTION #4
1. Bose
2. Navigation - Updated NAV software to latest rev.
3. Single CD
4. PIE CD CHanger adapter for Alpine with M-BUS AUX-in.
5. Rio S35 Sport, headphone jack, no line in.
6. PAC Ground Loop Isoloator for Audio

This is working fine for me, my "EX 1" flashes but audio and my nav does not cut out. I can leave the Mp3 player off, and the the EX 1 still flashes, I can have the NAV open or closed, no issues.

So with all these different results it seems this solution is a little bit of a crap shoot.

I have an IPOD incoming I will be using with the Belkin auto kit, I'll post on the results...

S

I don't have the updated NAV software. I am wondering if that is the problem I might be having get my PIE adapter to work.

My Adapter's just arrived today, i am going to try it tonight, and let you know about Option 2...i believe it will actually work, if you have a high enough output...

'affenage' mentioned earlier an idea about turning up the volume to try and clear up the EX-1 problem. Line-In inputs expect a 1V P-P signal such as what comes out of your Levinson at home. If you're using the earphone output, you really should crank the volume up all the way to get that 1V signal. 3G iPods have a Line Out in addition to the earphone output - it's the best choice for this kind of application.

Nobody reported results about the original post. I'd be interested in knowing if it clears up the EX-1 issue - or perhaps even fixes unworking installations. I'm buying 'ectomort's tape unit... I really do think OverLOAD will succeed; I think he got into the project and found out how do to it *right* and is doing just that. Still, I monitor this thread as a fallback.

liquid,

I thought you said you had option #1? In your previous post it says NO NAV + Changer, but your last post mentioned option #2. Which is it? The reason I am asking is because I am an option #1 myself and I am trying to watch and see who has luck and who does not...

I am also interested in seeing if cranking up the headhone out will have any affect.... This would not help us XM commander folks who would only have line out's to deal with... but it would help out others. If this is the case, a simple amplifier circuit might do the trick, but we should wait and see....

Here is my report.
Bad news, but a little bit fun to see "EX 1" displayed in the LCD pannel.

My Car Option#1

1) 6 CD chnager
2) BOSE system
3) No navi
4) JDM RX-8 type-S (received 2003/06.)
5) MAZ/PC-ALP with M-BUS AUX-in.(MAZ/PC-ALP Serial No. 403440012)


I tried with a headphone jack of my portable MiniDisk player.

"EX 1" flashed( correctly speaking, only "1" part flashed) and I could hear the output of my MiniDisk player through the factory audio unit.

But cut out after 30 sec. Maxmizing the output volume of the MiniDisk player did not help.

I disassembled MAZ/PC-ALP module then found my version is ver1.3 printed on the circuit board.

Thanks for such a detailed report Yuhki.

It should be obvious to any third party monitoring this thread that the users here need a solution and are willing to do what it takes to get it.

For those of you who have already attempted this install, please keep the facts comming.

BritSti and anyone else that has successfully installed this module without problem: Can one of you please open your module and get the rerence numbers off the board as Yuhki did? If you have a much lower revision board then it's possible that PIE removed the ability from later boards due to a legal binding of some sort or the desire to release their own custom AUX solution.

Thanks to everyone that's tried to help make this solution work. I speak for myself and I'm sure others when I say that it's very depressing this solution is not working. We need a solution!!!

i meant option 1, and i ran out of time last night, so i am doing it in about 2 hours.

Not to sound like a bottom-feeder, but if anyone wishes to sell off their failed PIE converter, I'm interested. My plan is to order a Dension Alpine ICELink and try it out. I've got a 2004 Mazda 3, stock HU/integral 6-disc changer.

OK...so i have mine hooked up, and i tested before i finished wiring...works fine.

I have option 1, i have installed a splitter temporarily, until i make my switch, right now i have hooked up the MP3 player, and it works fine...i am going to finish hooking up my XM commander, and get it all put back together.

Then i will take some pics for the complete install, and post them...

ok, so my install is complete...and those little clips are a serious PITA...i hate them...anyway...I installed my PIE under the top section of the dash, and as soon as i have some more time, i will relocate my XM unit here as well. (Idiot's at Car Toys didn't put it there like i asked them to).

Here is a picture with the PIE hooked up...

Like i said earlier, i have Bose, 6CD, no NAV, and mine works fine...just don't like the blinking EX 1...but oh well...

Congrats. liquid.

Seems you have the same configutation as mine.
Do you have any idea on differeces between you and me ?

what is your MF date on your car...maye they did something different to the disk changer...who knows...next time i take it out, i will look for labels on the changer, and the PIE unit, and post them...sorry i don't have any more information for you.

liquid,

That top panel, does it just pop off with the clips? or are there any other screws you had to remove. I LOVE the location to store the PIE, NICE FIND!! Did you do anything to strap it down so it doesnt rattle around at high speeds?

-RX8J

nothing to tie it down right now...but i took a few corners at speed, and raced down a street earlier tonight, and got no rattle...i found out how to take out the top panel in the music keg install thread - you can find it here ( http://www.rx8club.com/showthread.php?s=&threadid=13097&highlight=music+keg)...it was only 4 more screws...once you get past the stupid clips in the head unit everything is easy...

Like i said, i am going to put the XM unit up there as well, and probably velcro them both down either tomorrow, or next weeked...depends on how adventorous i am feeling tomorrow...since my garage is usually about 106 according to the Ambient Temp gauge on my 8.

Hope this helps...PM me the switch design...i can't wait to get that setup, and fabricate my plastic face plate for the commander...

BTW you can check out some extra pics of my car at http://www.havenbbs.com/rx8/images it's kinda empty right now, but i will post more next week.

liquid,

The link is broken, but just remove one of the http:// and it works fine. I see the other 4 screws you mentioned, thanks for that I like that for my install as well.

I just ordered my PIE converter, I realize that it might not work, but I had to take the chance. I will post my results. I am option #1 Bose, CD Changer, no NAV.

Sorry I have not gotten you that switcher scematic, I got a sinus infection and have been really out of it the last few days. I will get it to you after the holliday weekend (I left the paper with the part numbers and scribbles at work). As I said I have been out of it!! You will have it Tue/Wed at the latest, as I still have to turn it into something electronic that I can post, right now it's still on paper.

I will also post a link for anyone else who wants it. It is basically an input switcher. Two in's, one out; so you can switch between two different input sources (MP3 and XM for liquid and I). The circuit controls a relay and an LED (light), I am going to get a blue LED to match the blue car.

It's a simple circuit, but I already calculated the resistor values for some different type LED's and I have allied part numbers and prices at work, and dont want to do it all again. The whole project will cost about $30 to build including a nice small project box to house the thing, and all of the components can be ordered online from electronic parts suppliers. I will be sharing the scematic, but when i do, realize that it is just designed on paper, and I will NOT have had a chance to test it. Use it at your own risk. Also, once I see that the PIE solution works, I will proceed to building one myself, and I will take pictures and document the whole process.

Happy 4th to All!!

When you send me the electronic copy, i will throw it up on my webserver for long term storage. And As soon as i get the specs, i will be building it and testing it...so more details to follow.

Not sure where the extra http is coming from, when i edit the post, it only shows the one...hmm....oh well.

Hey All,

**DISCLAIMER**
THIS IS UNTESTED AND IN BETA RIGHT NOW. DO NOT BUILD AND INSTALL UNLESS YOU HAVE SOME EXPERIENCE WITH ELECTRONIC CIRCUITS. DONT CRY TO ME HOW IT MESSED UP XYZ COMPONENT. USE AT YOUR OWN RISK!

That being said, it should work (on paper anyway).

I finished round one of my input switcher. I will be building one after I receive my PIE and make sure that it works, if not then I will have to figure out something else for an AUX IN (probably one of the other known methods).

Either way, This circuit uses a switch to turn on/off a relay. I also added a nice blue LED to match my car ;). When you flip the switch, the relay closes the normally open contacts and switches inputs. When off, it connectes the normally closed to the common car inputs.

I included part numbers from an electronics catalog I had, but you should be able to get the parts just about anywhere. The only one I had trouble finding was the relay. This one I found will handle all of the left and right, positive and negative contacts. I am not sure about interference because this is untested (have I heard that before?), but I think should be fine, especially if you dont have both inputs playing at the same time (some testing will see if this needs more work or not).

You can check out the scematic here:
http://www.extrapoint.com/caraudioswitch.jpg (www.extrapoint.com/caraudioswitch.jpg)

liquid, can you grab a copy of this and put it on your server, this is a server I run at my house, and although it's static IP, I am a software developer and I play alot (take sites down while I promote code).

Hope this is helpful to everyone! If you have comments or questions feel free to discuss.

-RX8J
P.S. You will need a project box and circuit board, but RatShack has them for like $3.

I still need to rip the headunit back out to get the serial number for my PIE unit but I did run across this issue yesterday.

I have never had my aux-in cut our or go to nav while the radio is turned on however, if I leave my Ipod playing through the aux-in and turn the sound system off, the nav screen immediately turns into the Japannese TV tuner screen.

Does anyone else have the same scenario or does the Jap tuner screen pop up all the time for you??

So the solution is still working fine on my Bose, Nav, single CD setup.

S

I have the 6 disc changer with Nav and I can't get it to work...I get the 15 seconds of music then no sound and the Japanese TV tuner setup...Anyone that comes up with a fix for this is a god in my book as it solves everyone's problems for getting AUX IN for our 8s!

what source are you using, and is your nav unit up at the time?

I am using my carputer...P4 2.0ghz. I have tried it with the volume all the way up, and with the Nav both up and down. No Luck...Have not tried different input sources, but I can't see how that would matter...the volume coming off the box is fine...Right now I am having to use the AUX-IN tape mod which works, but would rather have the PNP

hmm...odd...i wonder...i will have to try and find someone near by so i can see what the nav is doing when it is on and off...and how the PIE interacts with it...any takers in the DFW area?

I just finished installing my PIE aux-in setup along with my DVD-in system and the power feed for my Rio Karma Docking station.
My RX-8 is a GT with Bose, Nav, and mp3 player.
Yes, mine does this also anytime the aux-in is selected and then the audio system is powered down. No big deal, just interesting.
My PIE setup works beautifully, and I even have two different sources wired to it with 'Y' cables (Rio Karma and Blaupunkt DVD player).

I just had success with the PIE installation myself. Non-Bose, Non-Nav. Using a Delphi XM Roady. The car was manufactured 04/04 so newer built cars are still allowing this functionality. The PIE adapter was just purchased (from Logjam electronics) last week so newer builds are still allowing it. I also used the Mbus-RCA adapter from PIE as well (bought from crutchfield for $15)

Notes:
- anybody who re-installs that hidden screw needs to have their head examined
- you have to turn the car off and on again to sense the new connector after install.
Since I have Auto trans, I had to turn the key to on and put it in drive to have enough room to pull the radio out. I powered off the radio, plugged in the cable, hooked up my XM Roady to test before I put everything back, turned on the radio, hit the CD buttton twice, nothing happened. Not even the EX 1 showed up. i was thinking that since my car is a recent build, that they changed the systems to not allow this funtionality. Then I thought that maybe the cars electronics need to sense the change during its boot process and thankfully I was right.

XM Radio has never sounded so sweet!

Congratulations Southsider...

On another note maybe Overload is reading this (Hopefully)!

The problem that I see with this unit is that by using the AUX in connecter on the M-Bus there is no signal telling the head unit that there is a CD in the changer (because there is no cd changer). I bet Overload could figure out how to fake that signal through these connectors. so we could use it. I for one am willing to loan my unit for this purpose if he could figure it and send me back a working unit.

What do you think overload?


I'm having enough fun just finishing up the Aux-Mod right now ;).. I don't need another project yet.. Although I'd bet that there's just 1 very simple message that the m-bus adapter needs to send. Either the PIE or the m-bus to RCA adapter could be re-programmed (by the people with the source code, not me..) to simply always send out the disk1-track one playing message. That would at least prevent the nav system from taking over after failing to find a disc..

Regards,

OverLOAD

hmm...here is an odd thought...the people with 6 disk changers that have it fail after 30 seconds...are you changers fully loaded with 6 disks? If not, what happens when you put all 6 disks in and then try it. Just a thought...since everytime i have used my aux the disk changer has been fully loaded...

when i get some time today, i will try pulling some disks and see what happens...

Hey everyone. Quick question.

Does anybody have this working with a bose system, 6 CD changer and NAV?

Thanks.

Hey all,

I installed my PIE/MBUS solution today. All is working fine. I took pictures of the install, BUT I messed up the ashtray lid. I am going to order a new one and put the pics up when it's done. Next project will be the switch I posted the scematic for in a previous post.

I have a Bose CD Changer, No NAV and no Tape (or Mini Disc).

Does anyone know where I can get a whole new ashtray unit?

-RX8J

RX8J...is your changer fully loaded???

Yeah, I keep it full. I installed the XM Commander as my source and I tried turning the units on in different orders (radio power then XM power and the reverse). It didn't make a difference, I can NOT get the unit to not work (Which is good news for me).

I will try it out without cd's in there and different combinations of that. I also notice that if I hit the display button on the radio it shows 6 CD's in the display (when it's on EX 1), I wonder if the ones that are not working show the same.

-RX8J

Hey everyone. Quick question.

I do in the UK, but I ordered the interface from ICD in the UK, who make their own version of the PIE interface, MAZA1. Just installed it and all is fine.

Lysander

I tried removing lots of combinations of discs from the changer, but the PIE still works fine. I am not sure why it is not working for some....


-RX8J

Hey all,

Talk to Rosenthal. Whenever I ask for an odd piece Tommy always comes through.

My PIE install went nice and smoothly, everything fit, etc,

But it doesn't work completely. I have the GT package with the Bose HU, no NAV, a MP3 CD & Tape unit in the radio.

After going into EX mode, the 1 flashes continuously and 30 seconds after that, it powers off the whole HU. Not quite what I was expecting. Just figured I'd post my results.

The audio quality is a little better than the Tape line-in hack that I've done. The very low-level tape motors can be heard as a low volume low frequency hum through the tape adapter when set to MAX volume, while the PIE is a little quieter. I can still hear the HU BUS communications through both inputs when listening to silence at max volume.

Regards,

OverLOAD

Just finished the install and it works well with the base audio system. One observation: you don't need to disconnect any wires from the unit. Pull it out, twist it slightly to the left and plug in the PIE adapter. The connector is towards left, next to the antenna (thick black wire). Touch to find it. The locking tab points down. Just make sure you push it all the way in - needs persistance :o) Pull on the connector - it should not go out any more when it locks in place. And test that everything works before you put everything back together. Also, I didn't bother puting back the bolt.

Anyone else with Option 3 (Bose, No Nav, Single CD Changer), get the PIE work work? Affenage in an earlier post said hers set up worked (perhaps an early PIE purchase, before disabled by mfr?) and another poster, Driver 8, who said his 2nd Gen IPd and XM Commander wouldn't work -- 15 seconds then no audio.

I'm so frustrated that I'm willing to take a chance that the PIE set up will work for my external MP3 player or, if I have to, purchase an IPod mini.

Well mine worked, but I have the Bose, no Nav and CD Changer). I tried to track these parts down back in late winter. I had used these stuff for my previous Neo Jukebox install. Gave up waiting on them and went with a slightly modified Overload tape deck option (which wil be up for sale shortly). Glad you brought up this thread starbucks.

Here you go guys:

Discount Car Stereo
www.discountcarstereo.com

MAZ/PC-ALP $76.99
ALP/M RCA KCM-122B Aux in Apapter $19.99

Good prices but no return options.
I just ordered these two items through this site. Their prices are slightly cheaper now (MAZ/PC-ALP $72.98 and ALP/M RCA KCM-122B $18.98). With UPS ground shipping and $1 handling, I paid $100.57 for the complete order.
As for no return options, that doesn't seem to be correct. According to their terms:

Returns due to incompatibility: Parts purchased that proves incompatible may be returned for credit or exchange.

Returns due to customer ordering the wrong part: If for some reason you ordered the wrong part, (not based on our description) you may return it at your expense for exchange or credit. If we are unable to provide a replacement part a refund for the full amount of the merchandise (not including original shipping) will be issued and our 10% restocking fee will also apply.

Returns due to wrong description: If we have described an item as "Compatible" and it is later determined that we provided an incorrect description, we will gladly issue a return label for you to return the part (s) at your expense. We will also try to find a suitable part and ship it at our expense. If such part is not available we will credit your account in full.

Seems to be pretty good, actually.

I'll let you guys know how my install will go - for the record, I have the non-Bose, no CD changer, no nav version.

Instead of buying the casette deck and doing the aux in hack, can we not do something like this?

http://nxmx5.com/aux_in.html

Taping directly into the socket that the casette player plugs into seems cheaper and easier.
Yes I know it is for a Miata, and the older bose systems but wouldnt the principles be the same?
Or will it not work due to the casette player needing to communicate with the head unit?

Well, on the RX-8 the cassette player doesn't plug into that socket. It plugs into a completely different connector on the bottom of the HU, and that is the connector that seems to be unobtainable by mere mortals in quantities of less than 100,000.
We have a connector that looks like that one on our RX-8 HUs and that is the one that the PIE adapters connect to. I think it is for a JDM TV tuner.

Could we not then solder directly into the socket on the bottom of the head unit?

Yes, that is an option that some may want to pursue. Overload has said that solder-in kits will be available soon if he can't get a plug-in module going. This is MY recollection of what Overload has said, and I may not be 100% accurate. Don't hold Overload to what I say.
The drawback, apart from the soldering itself, is that it will almost certainly void your warrantee on the Stereo.

Hazaaaaa. Found a UK supplier. Mines on it's way.


You couldn't spill the beans on this one, looking around for something like this myself.

Did you find a UK supplier, or someone in the US that will ship to the UK?

Wow... has anyone seen Alpine's new KCA-420i "Alpine iPod Interface (http://www.alpine-usa.com/products/leading_technology/leading_tech_kca-420i.htm)"? Here's what they say:

"Now you wonder how you could ever live without an iPod after owning one. What if there was an even better way of cruising to your tunes? Introducing the KCA-420i, the best in-vehicle interface adapter which allows you to cruise to your iTunes™! Simply use the KCA-420i to plug in your *iPod or iPod mini into a compatible 2004 Alpine Ai-NET head unit, and voilà! Get ready to groove to your iPod in your car.

Control Within Reach.

Plugging in keeps you in control. You can quickly search and listen to your iPod tracks directly from your head unit, and even use a remote control. The power to control key playback functions is at your fingertips.

Find Your Favorites Quickly.

With any 2004 Alpine Ai-NET head unit, QuickSearch™ keys, and the ergonomic rotary knob make it easy and extremely convenient to search songs stored in the iPod. You can quickly search through your collection by playlist, artist, or album and find exactly what you're in the mood for. The best part is, it allows you to search for music while enjoying your current selection. When you're ready for your next hit, it's as easy as pushing in the knob.

Song Title, Artist, and Album at a Glance

With every great navigable interface like QuickSearch comes great display information. The Alpine solution displays vital information on the head unit. Identifying your next song selection is simple when you can view artist, album, and song names during playback. All Alpine displays are specifically engineered for the vehicle, and designed to be clearly visible even in direct sunlight. The high resolution, high contrast displays make the information easily viewable from any angle. One glance is all it takes to see what song is playing while you keep your focus on the road.

Turn It Up!

As with any digital music and plugged-in portable device, there's always the fear of the loss of sound quality; but not this time. Since the iPod and KCA-420i are connected directly to the head unit via our patented Ai-NET BUS, it will playback all of the music information encoded on your iPod. The great news is that 2004 Alpine Ai-NET head units are equipped with a proprietary technology which enhances sound quality and restores lost detail to compressed digital media. Alpine is always focused on improving sound performance so you can hear the difference."


I don't know if or how this could tie into the RX-8 head unit via PIE products, but I didn't see the KCA-420i part number mentioned anywhere on RX8Club, so I thought I should bring it up. There's a protocol converter for Ai-Net to M-Bus... is it possible this could integrate the iPod with the RX-8 HU and steering wheel controls?

Yep, my PIE adapter was working just fine and then today I had it cut out.
"What the Hell?" I thought. This was working fine an hour ago.
So I tried fiddling with buttons --- VOILA!
When your PIE aux-in is not working right (20 seconds and then no sound and a Japanese TV screen if you have nav) the LED display is saying "EX " -- right? Well, press the "disc up" (#2) or "disc down" (#1) button until the LED display says "EX 1" and it will work.

Apparently Mazda has provided 6 aux inputs in the HU, but the PIE adapter is only using #1.

Hmmm, could the solution to all the others whose PIE's cut out be so simple? I hope so. How about those who only have the single CD player and also get the cut off after 15 seconds?

bob...that sounds alot like what i suspected...good catch, hopefully that is the problem everyone has been having...

Sorry to burst the bubble on this one but mine cuts out while it is Flashing "EX 1" Disc up or down brings it back for another 20 seconds then it dies again. BTW I have the Bose, with 6 disc and Nav

Werent there people who had the ex1 flashing and a system that shuts down?
I want to do the pie set up but it sounds as though the cd changer will not work either after it is set up for pie.
Those who are having problems, does this latest solution work, and do you have a fully functional cd changer and aux in?
Do you hit the cd button to cycle from aux to cd changer?
I dont see how shuttling the disk up and down button changes things but whatever works I guess.

Hmmm, could the solution to all the others whose PIE's cut out be so simple? I hope so. How about those who only have the single CD player and also get the cut off after 15 seconds?Even if you don't have a cd player at all you still have the "disc up" and "disc down" buttons. So it ought to work for everyone. I hope some of the folks who are having the problem will let us know if it works for themor not.

i have the changer and pie...hitting the cd button again changes from cd to ex1 and back again...disk up and down selects the disk i want to listen to...

i think its about what gets input first.. IF you have your input on then turn on the head unit.. it works ?? but if you turn off your MP3... or what ever with the head unit on it goes to T.V. Mode ?

Well, on the RX-8 the cassette player doesn't plug into that socket. It plugs into a completely different connector on the bottom of the HU, and that is the connector that seems to be unobtainable by mere mortals in quantities of less than 100,000.

yes it is

and what if we just want to send it analog audio ?

i have the changer and pie...hitting the cd button again changes from cd to ex1 and back again...disk up and down selects the disk i want to listen to...
Yes, hitting the CD button repeatedly toggles between CD and EX on mine too.
Hitting disc up or disc down selects which disc plays when in cd mode but selects which EX input (EX 1, EX 2, EX 3, EX 4, EX 5, or EX 6) when in EX mode -- at least that's what it does on mine.

i think its about what gets input first.. IF you have your input on then turn on the head unit.. it works ?? but if you turn off your MP3... or what ever with the head unit on it goes to T.V. Mode ?
Have you tried this? I just tried it on mine and with no input connected to the aux-in line, the HU went to EX 1 as soon as I powered up the car and it stayed there until I turned the power off.

bob how are you converting the Audio out of the DVD ?

and what if we just want to send it analog audio ?
Do you mean without the PIE adapter? Hmmm, I haven't tried that but I think that there is more to it than that because of the HU being able to select 6 different EX inouts when it is enabled. Now if the enabling is simply a dc connection (either to ground or to +12v) it may work -- that's what the older HUs did.
I'm thinking as I'm typing this and it occurs to me that we're using a 16-pin connector and two of those pins are (probably) being used to enable the TV/aux-in mode. This leaves 14 pins -- 6 aux-ins would use 12 pins (6 stereo pairs) leaving one for the TV audio and one for a common signal ground. This is all supposition, but it's a possibility and the TV mode does not display EX on the LED display, so it must be something other than one of the EX inputs.
Now IF the above is true, and that's a big if, we could just wire up the "enable" pin to +12v or ground (whichever it needs) and have our aux-in(s). Of course there is still the problem of identifying what each pin does :confused:

bob how are you converting the Audio out of the DVD ?
No conversion as such. I'm just connecting the R/L audio signals from the DVD-ME3 to the PIE R/L inputs through a ground loop isolator. I have two other audio signals connected in parallel with the DVD.
The GLI isn't needed unless you have other audio sources connected in parallel to the DVD audio. It seems that the DVD-ME3 shunts the audio lines to ground when there is no video signal, including when it is powered off. This is probably to prevent a burst of loud white noise when a video signal drops to an unusable level.

ok so the pie takes a analog rca connection.. thats all i need i just want to get a good clean audio input from my Avelectronics box :)

got a good source for the parts ?

I am with you there!

Parts? Stereo cable, RCA to RCA -- anywhere that sells audio cables.
If tou're talking about the Ground Loop Isolator, I got mine from Radio Shack. But I don't think you will need one.
How is the audio signal from the Avelectronics box? High, Low, "About Right"?

no i mean the pie ! :) i want a peice

Oh. I got mine from Logjam Electronics (http://www.logjamelectronics.com). Part #s are PIE MAZ/PC-ALP and PIE ALP/Ai-RCA. Make sure that you plug the 16-pin plug into the HU connector all the way -- it fits pretty tight.

well do..

ok just orderd it.. Looks like this is the best way to get Clean audio into the head unit..

And it seems the fix is just to switch to the prpoer input? or do you have to cycle through it ? all the time ...

ok just orderd it.. Looks like this is the best way to get Clean audio into the head unit.. I think so, withj the possible exception of the unit that RandyP (?) is getting from Japan. That just might provide multiple inputs!

And it seems the fix is just to switch to the prpoer input? or do you have to cycle through it ? all the time ...Mine only did the cut-out routine one time. I've been using it for nearly a month now and it just stays on EX 1 whenever I poke the CD button (or poke it twice if it was on CD rather than EX when I switch to it). Cycling through it is only needed if it cuts off.

Does anyone know if PIE changed their stance on this converter or if they upgraded their firmware? The reason I'm wondering is because the text on LogJams website (http://www.logjamelectronics.com/piemazpcalp.html) has now changed. Now it reads:

"P.I.E. MAZ/PC-ALP CD CHANGER INTERFACE / AUXILIARY INPUT CONVERTER"

PIE has always said that their module couldn't officially be used for AUX input. But the LogJam site clearly states

Or, with the addition of the P.I.E. ALP/M-RCA cable (see below for ordering info), you can create an auxiliary audio input where you can connect any audio source, such as an iPod, portable CD player, DVD player, any audio source you want, to your Mazda factory radio without using an FM modulator.

And it lists the 2004 RX8 clearly on that page. I'm wondering if anyone knows if PIE changed their stance or if LogJam is willing to run the risk of it not working for some people.

I for one just completed my order. I also printed out the product information page that has all the verbage I just quoted. I'm going to keep it around in case it doesn't work for me. If it does, great, if not I'll simply ask for a refund.

hehe that is meee with the unit from Japan.. It so far will not just plug in.. We are trying to find a sourc in Japan for the connecter to mimic the Pie unit.. Soll this is all relative..



Hed Mods.. can we please combien all 3 of these threads to one...

Here is a great installation tutorial for the solder-in solution.

You can use the instructions for installing the PIE device. I should have mine on Wednesday.

The author suggests using s CD-R of scilence to keep the AUX input enabled.

http://www.whatsmyip.org/ipodrx8/ (http://www.whatsmyip.org/ipodrx8/)

yes.. thats ok to.. but the pie plugs into the head unit... so maybe we need the cd of silince if the switching inputs does not work.. I now know from talking with peeps in Japan that the Head unit controlls the Video and audio.. Itis possible to get a video and audio input into the same connector that the pie is using on the HU. it may be possible to hack the pie connecter with the video input and get both :)

keep us posted as i will to .. mine will be here tommorw. Since my car is apart from the MAzda RCA input installl..

The place I ordered mine from (www.discountcarstereo.com) has a similar verbiage, however they write:

You may (in some instances) use the MAZ/PC-ALP interface with Alpine M-Bus Auxiliary Input adapter to connect an Auxiliary source (iPod, Walkman, DVD audio, XM radio, Mp3 player etc) to the factory radio. The MAZ/PC-ALP is compatible with Mazda vehicles listed in the "Order Option" drop-down list, please make your selection based on vehicles listed there.
Note the "may (in some instances)" :D - they are a bit more careful.
Still, they clearly list the RX-8 as being compatible with this module in that drop-down box, so if mine won't work, I'll also ask for a refund. This Web vendor has a pretty good return policy (as I posted in the previous page in this thread), so I guess it should be OK.

ok i installed mine sounds Great.. but shuts off just like the others.. Itriend switching the inputs.. I tired switching the Mode to cd ex ... but still does it.. Turn on system it gets signal then shuts down to T.V. screen

I can only get it to say EX 1 it does not cycle thur to 1-6 like yours..

:( ....

Have you tried this? I just tried it on mine and with no input connected to the aux-in line, the HU went to EX 1 as soon as I powered up the car and it stayed there until I turned the power off.
i can still switch out of that back to cd...

ok so i can switch between ex 1-6 now.but when mine goes to the T.V. screen it shuts donw the HU.. i have to turn it back on first....then it runs fo 20 sec .... switching the Ex inputs does cycle thru 1-6 but when i go back to ex1 it has no audio.. I have to switch back to cd the ex and it works for 20 sec..

yea, i cycled through the ex-1,2,3,4,5,6 and when i got back to one, i had to switch modes on my HU to get audio back...kinda wierd...it may have something to do with the whole 20 second thing.

and you have no luck gettin git to work longer than 20 secs??

Damn! I thought we had it solved for a while there.

why does this work on yours ????


Its like the HU is shutting down with no signal.. I think it needs some input on that Video input pin..

why does this work on yours ????


Its like the HU is shutting down with no signal.. I think it needs some input on that Video input pin..

Thew's must be right...usually auto-sensing signal switchers use the VIDEO IN as the reference for switching to that signal set...in otherwords...the audio wont work unless there is some sort of signal going through the video in...for NAV owners and maybe non-nav too...the pie adapter is neglecting the video signal and is why NAV owners cant use the unit

yes i think this is why.. but now we need the pin out of that connnecter.. I know there Video there because the JDM t.v. reciver uses that Plug. so we just have to give is some juice....
I even did this wiht the Nav unit dissconected. The Lcd screen still went to JDM tv after 20 secs.

and how come this works in Bob's 8 i dont get that.

just got this email

Subject: PIE MAZ/PC-alp works great then shuts down


This works great for about 20 secs then it shuts down the HU and i have to turn it back on to make it work for 20 secs again.. Help

------------------------------------------------------

just got off the phone with PIE.. the guy was very cool.. hes talked to a few of us :)
he said it only works on the Mazda MPV van.. and that anyone selling it that says it does work on the 8 is just assuming it works on all Mazda's . he said they paln on making one specfic to the 8 but had no idea when..

SO like I said bob.. what the helll is diffrent about your set up. You and i are using almost the same setup... Spilll the beans ....

probably fibbing that it works in his 8 (maybe he doesn't even have an 8) ;)

I am woundering if it has to do with his power source ? you made a power supply for all your gear? and tell me how you are getting the DVD into the LCD again.. did you use the pioneer box?

ok a Nav vision.. i found it in the fourm... I remember now.. Well i tried with the output of my dvd direct to pie and the avbox as well.. nothing diffrent

.. so I am back to your power source ? does not make sense ..
it is very clear that the HEad unih needs to see some video in that same interface....

exentric and Tamas,

Please keep us updated on whether your PIE works for your external devices. I have the Bose, no nav, single CD, set-up. If yours works, I will be ordering right behind you.

I've replaced the Bose tweeters with a pair of NX30 tweeters and am ready to take on the HU.

OK.
I installed it and it doesn't work. I get the flashing "EX 1" display and it shuts off the HU in 25 seconds.
I've tried all kinds of key-press combinations and various loads in the CD changer to no avail.

I have the Bose with the OEM 6-CD changer and no NAV.

ok a Nav vision.. i found it in the fourm... I remember now.. Well i tried with the output of my dvd direct to pie and the avbox as well.. nothing diffrent

.. so I am back to your power source ? does not make sense ..
it is very clear that the HEad unih needs to see some video in that same interface....
I seriously doubt that it is a power supply question since my PIE has worked with no additional power supply at all when testing. I was using internal batteries on the mp3 players then. The PIE gets its power directly from the HU.
No, the HU does not need to see video in that interface; I hooked up the PIE directly to an mp3 player and nothing else and it worked. Besides there is no way to get a video signal to that interface; all it is connected to is the PIE adapters and thence to an audio signal.
I wonder if the order of connecting the PIE adapters matters? I connected the two PIE units together and then connected them to the HU and then powered it up. I doubt this matters.

why two pie units? and how did you hook them both up?

He means the MAZ/PC-ALP unit and the MAZ/M-RCA cable adapter.

What I'm wondering about: does this mean that the Alpine CD-changer (for which this PC-ALP unit was originally designed) wouldn't work with the RX-8 either? That'd be interesting, considering that the PIE's own Digital Protocol Technology Application Guide clearly lists the RX-8 as being compatible.

If that works, then what does the Alpine CD changer do differently than the M-RCA cable adapter? It seems that the CD changer must then give some signal to the PC-ALP unit that is not there when the cable adapter is used.

AHH...ok...i thought their may be something new that would allow me to hook up even more to my HU...

OK.
I installed it and it doesn't work. I get the flashing "EX 1" display and it shuts off the HU in 25 seconds.

your missing the Point.. The HU DOES WANT TO SEE VIDEO.. The Hu controlls the Video switch for the JDM T.V. unit. it allows 6 A/V inputs... .. I think yours is working becasue you have broken a wire in your Plug.. you said your pie connecter was very hard to insert.. Mine was not hard.. it was tight but did not requier any really effort.. I did try reseating this .. nothing. If its not in the PIE then it should not be working on your car.. What else could it be...

Back to the video.. I am convinced that we can make this work if we can find the pinout for that HU connecter. it just needs some voltage to keep the Line open. ....

PIE says No.. The HU is looking for diffrent data then the PIE MAZ/PC-ALP is supplying.. It is only tested to work on the HU in a MPV van.


Words from his mouth! ..

thew is right...we need video in to get the Nav working...sorry to Bob but he probably did damage his HU...maybe not severly but possibly a short causing an audio signal to trigger the video in recognition and the acceptance of the audio in...fortunately for bob he already has his video setup...

some of us do have the video setup but want the oem in...better signal...more control through the HU...OEM style (doesn't void warranty)

PIE says No.. The HU is looking for diffrent data then the PIE MAZ/PC-ALP is supplying.. It is only tested to work on the HU in a MPV van.
In that case, their own protocol technology application guide is wrong. It lists the RX-8 as compatible with the PC-ALP (among others, not just the Mazda MPV). I have it up on my screen right now where it says so - straight from their Web site.

Update!!
from Logjammer Electronics
------------------------------------------------------------------------------------------------------
Hi Matt:
After a lengthy discussion with P.I.E.'s tech support people this morning, they indicated that the MAZ/PC-ALP has been tested in an actual RX8 and works as indicated in it. Additionally, they have had no feedback from any of their RX8 owners/customers that would indicate that there is a compatibility issue between the MAZ/PC-ALP and the RX8. Therefore, the normal conclusion would be that the MAZ/PC-ALP you have is defective in some way. So, if you want, we can send you another MAZ/PC-ALP in exchange for the one you have and hopefully, the device will work as you expected it to. Let me know.

Thanks,
Jim

taken from the pie site !!

There are a few that work...the ones i have heard the most about not working, are systems with NAV. I would ask Jim if PIE tested with or without NAV.

At least that is my feeling...mine works, but i don't have NAV.

At least that is my feeling...mine works, but i don't have NAV.Neither do I and it doesn't work for me.
The problem is deeper than this.

I imagine the solution is going to be as simple as pulling another pin on the HU connector to ground.

thew is right...we need video in to get the Nav working...sorry to Bob but he probably did damage his HU...maybe not severly but possibly a short causing an audio signal to trigger the video in recognition and the acceptance of the audio in...fortunately for bob he already has his video setup...

Nope, I didn't break anything putting it in. The connector just fits tight, that's all. It would be easy to insert it part way and think you have it in all the way.

And I repeat, there is no video signal going to my HU.... unless it's a stock video signal from the nav system, and there is no indication of this in the wiring diagrams for the RX-8. The nav system feeds an audio signal directly to the left channel power amp when it is "talking." It also mutes the signal from the HU to that same amp at that time. There is no other connection between the nav system and the audio system. The video is sent from the nav system's dvd drive directly to the LCD monitor. I am going back into the guts of my car soon to finish up some switching for the rear-view camera and I can completely disconnect all video sources from the front half of the car and check to see if audio aux-in is still working. I'll report findings here.

If the "aux-in enable" trigger is just a jumper like the older units was, then it appears that my PIE adapter is making this connection and PIE should be able to fix or replace the ones that do not do this.
Yeah, if the OEM unit becomes available, I would like to use that too.

Heres one more thought.. As i was removing my Pie unit today. I tried a few things.

With the cable connected but the interface box removed .. it does the same thing.. ex 1 flashes and then shuts down after 20 sec.

With the box pluged into the cable and the rca cable out of the loop same thing..

Then i opened up the box and found the main chip thats on the PC board was not seated all the way ! I reseated it and reinstalled the unit.. and it ran almost 40 secs before it shut off.. Then i took it all out and put it back in the box.. And read the install sheet again..

It does say to Disconnect the battery, hook it all up then reconnect the battery. I only disconnected the HU form the Car.. I am woundering if after all that the battery needs to be disconected to clear the memmory of the HU.. I say this becasue after i took out my PIE unit and reinstalled the HU.. When i turned it back on i got the JDM t.v. screen.. I had to turn off the HU again and wait a few mins.. then it worked like before.. NO T.V. Screen

Hey MazdaManiac did you dissconnect your battery before installing your PIE ? if not go out and dissconect it.. wait a few mins and hook it back up.. then try your HU... Maybe thats all were doing wrong.. Also your Chip may not be seated all the way as mine was..


We will see i have a replacment unit comming from Log jam there very good about this. ~~~!

For what it's worth I didn't disconnect my battery (or my HU) when installing the PIE unit.

this is very confusing...thank you bob for all your help

For your edification/education/stupification i present this:

Now, if someone wants to figure out what needs to be addressed and how...

areyou getting a new one to?? or waiting for me to get mine..

Waiting. I don't have the time or patience to pop my dash apart at the moment.

i have just now put mine back in.. Not sure when the replacement will be here.. AT least its just the HU ... I had the whole thing apart to run RCA cables thru it.. My new RCA input is so handy :)


And so do we belive that 80% of the PIE boxes are not working cause there bad ?

And so do we belive that 80% of the PIE boxes are not working cause there bad ?
No. I think there is another control issue. But I could be very wrong...

me to :(

still cant get why it works a few 8's but not all
or none

this is very confusing...thank you bob for all your helpYes it is very confusing. There must be a logical reason for what we are seeing, but it is not apparent yet.

Subject: FW: PIE MAZ/PC-alp works great then shuts down


Matt:
I have not sent a replacement as yet because I talked with PIE's tech support again today. I was thinking about your order this morning when I got your email that asked to also send a replacement ALP/M-RCA. It was then I realized for the first time (duh) that you also ordered the ALP/M-RCA which means you are attempting to get an aux in rather than connect a CD changer. My discussions with PIE yesterday was regarding a CD changer install and that is why they kept saying that they hadn't received any calls about a installation into an RX8. So I called PIE this morning, and talked to them at length and they told me that the MAZ/PC-ALP & ALP/M-RCA combination has only been tested on the Mazda MPV. PIE indicated that it would NOT work in the RX8. They also said that fact was verified by the way the device is acting, by working for 30 seconds and then cutting out. They indicated that the headunit wasn't receiving recognizing that a CD changer was connected so it would switch back to radio operation after 30 seconds.

Not being one that believes everything he hears, I did a little research myself and found a couple Mazda forums where some folks are saying that it will work, and a couple forums where people have tried it and it didn't work. Therefore, if you could give me a few more days to sort this out, I will hopefully get a definitive answer on whether it should work and your MAZ/PC-ALP is defective, or that it never will work, no matter how many interfaces I send you.

So give me a few more days.



Thank you for your business and your patience,
Jim

MY Reply

----------------------------------------------------
Well its funny I am a member of the RX8club.com we have about 3 members that Can get it to work . the other 7 -8 that have it cannot..
When we say the Listing on the PIE sight begin to list the RX8 we thought they had made some kind of change to the unit..

Thanks for checking this out.. I am forwarding these messages to the RX8club.com forum as well.. That way maybe we can get this straight once and for all..
BTW it was that Forum that pointed me to you as a customer.
You are doing a great job..

Thanks again.

Maybe you will find out why it works in some rx8's cars and not others.

-------------------------------------------------------------------

So the saga continues. Although the guy at PIE told me the Alpine cd unit would not work either.. this does not explain why it works in some 8's and not others ! :(

Uggg.. Hey Mazda how bout some help here.....

So here is a dumb thought...how mant of the people that have it working other than me, have split the RCA inputs to two, so that they could hook up more than one device...maybe it is just that simple?

HU --> PIE --> AZ/RCA --> RCA Y Cables --> Devices...

Of course i can only use one at a time, but it still accomplishes what i want for the time being...just a thought...maybe someone can try this, or someone can tell me wether or not they got it working without the Y Cables.

I'm pretty sure that it is going to require a logic device to send M-Bus signals to the PIE adapter, tricking it into believing there is a changer present.
There are several good pages on the internet that describe projects that are way over my pinhead. Perhaps one of our engineer types could translate?

I just wanted to mention again that a couple people, including myself, have had perfect luck with the "CD aux-in hack." I've had it running since the beginning of March. It delivers crystal clear audio and I have had no problems since the install. The only thing that will keep many people from attempting it is the fact that you need to solder directly onto the CD player's circuit board. If done incorrectly you could damage the head unit permanently. With that said, it's fairly easy to accomplish and very cheap. Only parts: headphone extension cord (~$6), a ground loop isolator (about $20 from radio shack, and pretty much necessary if you're planning on using the car to power your iPod/other device), and of course soldering equipment if you don't already own it (~$20). I have the headphone extension cable peeking out of the little plastic cover piece that's at the front of the center console. The ground loop isolator and power cable remain in the back half of the console, with a couple wires and the iPod itself in the main (cupholder) section. Also, I use the Monster Cable Ultra-Low Profile charger due to the fact that it has a "Line Out" jack from the iPod.

As far as the install itself, I used the instructions posted by ectomort in the "DIY: Tape Aux-In" thread.

Again, this method does have some risk involved, so be careful if you attempt it.

Hope this helps, and let me know if you have any questions,

So here is a dumb thought...how mant of the people that have it working other than me, have split the RCA inputs to two, so that they could hook up more than one device...maybe it is just that simple?

HU --> PIE --> AZ/RCA --> RCA Y Cables --> Devices...

Of course i can only use one at a time, but it still accomplishes what i want for the time being...just a thought...maybe someone can try this, or someone can tell me wether or not they got it working without the Y Cables.
I an using 'Y' cables too, but I'm pretty sure that it worked when I only had one device connected. BTW, it works when all three devices are playing, not that I usually do this, but it was a test.

I just wanted to mention again that a couple people, including myself, have had perfect luck with the "CD aux-in hack."... The only thing that will keep many people from attempting it is the fact that you need to solder directly onto the CD player's circuit board.
That and the cost of the CD player. That's why I didn't go that route.

Bob, the CD player is standard equipment :)

The ground loop isolator and power cable remain in the back half of the console, with a couple wires and the iPod itself in the main (cupholder) section. Also, I use the Monster Cable Ultra-Low Profile charger due to the fact that it has a "Line Out" jack from the iPod.Durahl... the GLI and the Monster did horrible things to my audio... check out this thread (http://www.rx8club.com/showthread.php?t=35789). I did the Tape Hack after buying ectomort's tape unit. It worked great, until I tried the Monster as a power source. On my thread, I have recordings of what it did to the audio, and the engine noise it picks up. The GLI rolls off so many highs and muddies the signal up so badly, a cassette tape would sound better. I have a recording and waveform readout from it.

Monster doesn't say much about it, but you can hear that they have noise-attenuation circuitry in the iPod dock connector. Just switch the audio plug from the earphone output to the Monster line output, and you can hear the effect of the filter pretty clearly.

When I do the same experiment with the Apple Docking Base, the character of the music isn't changed at all. It appears that Monster put in the filter to block some of the noise... but even so, for me using the Tape Hack, the Monster fills the music with static and whines with the engine RPM.

Check out the recordings... I'd like to understand why ectomort reports the Monster is "perfect" with the CD Hack, while with the Tape Hack it is "perfectly awful".

I am as confused as any of you, I have the PIE solution working perfectly in my RX8. I have a Bose system with a CD Changer (no tape deck). I pulled the radio completely out, hooked up the PIE to the RCA adapter and viola it works just fine. I am feeding the signal from an XM Commander. I don't see what should be different??

BTW, I just finished building an electronic switch to switch inputs. I posted the scematic in this thread. I just wanted to let everyone know that it works perfectly! I have tested it in the house on a home stereo using a CD player in one input, and my iPaq (as a simulated MP3 player) in the other input. Hitting a button switches the sources to the Aux-In. I have not installed it in my car yet because I am fabricating a mount in my ashtray for the commander and I don't want to pull the dash apart again till I have both pieces. I also installed some extra lines to the switch for a couple blue led's. That way when I reach in my center console, and hit the input switch, the center console compartment will light up blue (just like my 8) to let me know the mp3 input has been selected! I have been taking lots of pictures of the input switcher, and the fabrication. I will post pics once everything is done. I am taking my time on it, but I should be done within a couple weeks.

Well, just wanted to let everyone know the switch works. Best of luck on the PIE problem.

RX8J - Do you have Nav and what is the build date of your car?

RandyP... I have a few things in response to your last post. First, I do not use the headphone jack on the iPod, I use the line out on the monster cable power cord. Any headphone jack severely reduces quality because it is optimized to be sent to the mini speakers in headphones, hence the severe attenuation you speak of. Next, there is a difference in our setups since you appear to use the tape hack, while I use the CD player hack. This could result in a very large difference in GLI performance. The theory behind the problem is due to the fact that ground is only a reference and not actually "0 volts." This normally isn't a problem because the entire system is usually connected to the same "ground." When you have something directly wired into the speaker/stereo system (as with our hacks), and then have another ground on the same system (the power cable), you end up with slight differences in voltages between the two grounds which ends up causing the noise in the system. Because of small variations in the tape unit vs the cd unit, and also where in the electrical circuit we wired in, there could be huge differences in output and attenuation. For example, if the wires you spliced into were made to carry 2.5 volts, and the ones I hacked into were made for 3.1 volts, the effect of the ground loop could be drastically different. Anyway, you may already be familiar with all of this, but I just had to take issue with someone indirectly claiming that my setup sounded "worst than a tape deck." I have played CD's right before/after playing the iPod setup, and while they do sound slightly clearer (probably more due to digital audio compression than system setup) I definitely don't have the severe attenuation and high frequency cutout that you seem to suggest. (And yes, I did see your post proving it did happen at least in your setup). As long as we both enjoy our music, we are both successful... I was just trying to help out some of the people who might not know about some of the do-it-yourself options to the aux-in problem.

Durahl

Well, add me to the list of people that the approx. $100 cable/adapter set doesn't work more than 30 seconds. EX is on the screen. The only thing that flashes is the number one. While it's doing this you can press the buttons on the radio to make the number go up and down. This is apparently for changing discs if you had an attached changer.

I have the stock cd player and nav. The sound through these cables is great and clear. Bummer that it only lasts for about 30 seconds.

It makes sense that it doesn't work because it's obviously awaiting info from a changer. Seems like PIE could make a version of the adapter to give it what it's looking for to spoof the HU.

Please clue me in if there are any improvements or new discoveries.

(Also, I found that I didn't have to disconnect the battery. The fuse box under the hood has a 30a fuse labeled BTN that seems to cover anything using power with the key switch turned off. Pulling this for 30 seconds and putting it back in successfully reset the clock and erased the stations from the radio.


Thanks.
Martin

bummer :( did you try spliting your inputs ? like above ?
I am reinstall mine before it goes back and try that if noone else does..

Now, if someone wants to figure out what needs to be addressed and how...





maybe we need to try to send left and right Audio Line level to the c,d,e,f pins on the HU..

Has anyone tried this ?

Bob, the CD player is standard equipment :)
My eyes saw "CD" and my brain read "MD".

maybe we need to try to send left and right Audio Line level to the c,d,e,f pins on the HU..

Has anyone tried this ?

I'd be willing to bet that this is what the PIE unit does. If anyone wants to try this directly, be aware that you do NOT want your audio source grounded to the car -- even through a power supply. This is because the c.d.e.&f pins are balanced inputs and not grounded. A permanent solution using these pins (if they do work) will have to include some sort of DC isolation - (transformer or capacitor coupling).

Let's not have anyone breaking their stereo here.

I am tending to believe that somehow PIE made a run of adapters that accidentally provide the "trigger" to enable the aux-in. Most likely one of the "unused" pins is going to ground.

Thew, you seem to have established a line of communication to Logjam and PIE. Can you ask them this:
Would PIE like to examine a unit that works with RX-8s? I would be willing to send them mine to examine.

Also, to narrow this down, if anyone who has a PIE adapter set that does not work is willing to send it to me, I will put it in my 8 and see if it works or not. That would nail down whether it's the PIE or the RX-8 that's causing the problem. If it works on mine and not on yours, then we know that is is a difference in rx-8s; if it doesn't work on yours or mine, then we know that it's a difference in PIE adapters. I could also see if it's the HU to Mbus adapter or the Mbus to RCA adapter that is the culprit (as long as I still have mine with which to compare, that is).

hey guys with Nav (that includes me :() I found this in the 'attention ipod owners' thread:

In the Wall Street Journal, they review the BMW/Ipod interface and mention an Alpine solution due out at the end of September. Spoke with a guy from Al & Ed's audio and he told there was an adapter so the steering controls could be used. It won't work if you have the navigation system installed...

So is there a separate wiring diagram for nav owners??? and may explain the Factory only option?

Thew the wiring diagram posted by MazdaManiac may be for the non-nav owners only but I'm not really sure

Folks,

Let's keep this thread on topic, meaning keep posts regarding the PIE adapter, good, bad, or indifferent. This thread is long enough that we don't need to waste space telling people how another solution works better.

Thank you.

ok bob .. lets talk... send me yours.. or ill send you mine... I Must figure this out.. in the mean time i may send some signel down the line to the HU and see what happens.

ok bob .. lets talk... send me yours.. or ill send you mine... I Must figure this out.. in the mean time i may send some signel down the line to the HU and see what happens. Answered in PM.
It occurs to me that the most likely answer to why some PIE units work and others do not is component tolerances. Some of them can be pretty large.

I'm hoping that it's on the PIE side of things, because then PIE can just change a component value (and it would be to their advantage to do so since we are a pretty good-sized market).

I'm trying to keep the technical "hacking" of the PIE module separate from this thread discussing the module. Since there is already another thread based on hacking the rear port, I've posted my thoughts there.

I have an idea for the people who have the unit cutting out on them. If your unit isn't working as expected, please see this thread:

Engineers: Can this be hacked (http://www.rx8club.com/showthread.php?p=476885&posted=1#post476885)

I'm hoping that it's on the PIE side of things, because then PIE can just change a component value (and it would be to their advantage to do so since we are a pretty good-sized market).

I believe the original problem may be in the protocol and that it would be possible for PIE to change it. After looking inside the module, I can see that there is a programmable PIC chip in there which is where the protocol conversion is done. That chip can most likely be repogrammed, but you have to have the right tools. Even if PIE fixed the problem, you would most deffinately have to send the unit back to them to get that chip swapped out or reprogrammed.

I came up with a new theory today (discussed in the other thread I linked to). Now I'm wondering if it is the head unit or the PIE module that is causing the sound to be muted...

I guess I could have just posted those thoughts in this thread. I was thinking the other thread to be more of a technical / hacking thread then this one. Regardless, we can discuss it here or there. I'd just like to see this thing work. I'll have to test mine Sunday because I'm much too busy the next two days.

hehe.. ive got them all so it makes no diff..

I am working with Bob will let you know what we find.

Called PIE tech support. They insist that the adapter will work, but with the RCA option that it isn't expected to work. They suggested that they are working on a one piece component that should be available in a couple of months. [don't know how much faith to put in that.]

he suggested I return the cables I purchased to the places I got them from.

Same here - I talked to a guy called Victor and he confirmed what was said here earlier: they only tested the RCA cable / Alpine adapter in the 2002-2004 MPV minivan. He told me that they are working on a solution but it definitely will be a separate device and not an updated PC-ALP module. They won't provide a fix or a hack to make these curent modules work. So if somebody's unit works, great - but there is no guarantee. Apparently they also told Logjam to change the description on their site so that it won't say that this combo will work with all the models the PC-ALP otherwise is compatible with.

I have no NAV. Not sure of the build date of the car I would have to look and it's late right now. I will post.

I think if we are going to get to the bottom of this, we will have to find two people in one area one that works, and the other that does not. That way those people could switch out components and verify if it's a PIE problem, or a radio problem. Until someone does that, it's going to be all speculation.

It's beyond my understanding that the PIE set up would work on some with the configuration -- single cd, cd changer, nav, no nav, bose, no bose, etc. -- and not on others of the same configuration. That doesn't make any sense. Either it should work or not. I can understand an occasional bad part, but not on the scale that appears to be the case if you read all the posts -- works for some, doesn't for others with the same set ups.

I just don't get it.

I just went to try using a different device as the player that had both headphone out and line out. Line out was the way to go. However...still didn't work.

I also tried with the screen open this time instead of closed. Sure enough, when EX 1 stops working, something kicks in and takes over the display from the NAV unit and puts a blue screen up that says TV 1 and a bunch of Japanese on one line. I found that if you press the MENU button on the NAV control, it gives you a submenu to ADJust the screen brightness and contrast. It will say Day Mode. If you turn on the headlights, it then says night mode and will allow you to customize brightness and contrast for nighttime separately.

It will also allow you to turn the screen off. It does seem to turn on again later when you kick it into the blue screen. SO -- now we know of a way to tweak the display settings at least.

Also, if while in this mode you press POS, it will exit this mode and go to NAV.

However, this seems to have no effect on the EX 1 issue.

Also found that if you press the Disc up or down button to change the display to EX 2 through 6, suddenly the sound goes off. I wonder if it is accepting input through one of the unused pins on the connector?

I also noticed that using the MUTE button does mute the sound as expected but doesn't prevent the TV 1 screen or anything.

Anybody think Mazda might tell us anything?

Also, the TV 1 screen seems to have 6 buttons across the bottom, and one that says AUTO-M. I can't help but wonder if there is a infra-red remote since the LCD screen looks like it might have a receiver window for one. Makes me wonder what other settings one might be able to access if there were such a thing.

Also...makes me wonder...for those that have this working, do you get the TV 1 screen with Japanese? (Assuming this really does work with a NAV package installed...I forgot if anyone had that combo working with Bose.)

Thanks.

MartinMine is Nav and Bose and my PIE input is working.
When it quit working for a while the other day I had the TV 1 screen with Japanese characters on the display, but not when it is working. It just shows my nav screen or my DVD/TV unit or my reverse camera.

I have no NAV. Not sure of the build date of the car I would have to look and it's late right now. I will post.

-RX8JThew and I are doing exactly that. Stay tuned for updates.

BTW, I tried my PIE aux-in with ALL the video sources completely disconnected today and it made no difference at all.

Update time.
The PIE adapter set works in my RX-8 as you all know if you've been following this thread. I just finished pulling my PIE parts and replacing them with Thew's set which doesn' work in his 8. They work just fine in mine. They have been playing for over 5 minutes now.

So, what's the difference in our 8s? Well, mine has the mp3 player and nav, so the presence of nav isn't the problem as was suspected at one time. I just wonder if the mp3 player is sending a signal that enables the aux-in in the HU? Perhaps a signal that remote CD changers send? The factory CD changer doesn't use this connector, so it might not provide that signal. But the connector is for the JDM TV module which WILL work with auxiliary devices such as the RCA cable that Thew got from Japan -- so a signal saying "I'm a remote device and I'm here" is probably needed at the port we are using. The Alpine changers apparently provide this signal. I'm wondering if my mp3 player is also providing the same signal even though it isn't using the 16-pin connector (it's probably on the same data bus).

Enough speculation. I've worked my curiosity up enough to pull the mp3 player off of the HU and see if the PIE stuff still works.

Further news as it happens.

I'm really confused now.
I pulled the mp3 module from the HU and installed the bare HU in the car. Powered it up, and the PIE aux-in was still working like a charm! I let it play for 5 minutes and all was well. So it's not the mp3 player that's allowing the PIE stuff to work. It must be some difference in the HUs. As I said before, it's not the presence or absence of a video signal, because I tried it both ways. And it worked both ways.

At this point I'm going to put my HU back together, put it back in my car, reprogram my radio stations, and pack Thew's PIE parts back up to ship back to him tomorrow.

Thanks for the loan of the parts Thew. We at least narrowed things down a bit, but we still don't have a fix for you and the rest whose PIE adapters don't work right.

Anybody else see anything that I'm missing here?

i assume you tried my PIE with and without your RCA spliters ?

and this was with and without my wireing harness?

just trying to get my head around it.. I really have a had time beliveing that your HU is not the same as mine..

What build day is your 8 ?
Mine is 04/03

My build date is 06/03. Not much difference.

Yeah, this was with and without multiple inputs; with your harness; with my harness; I tried every way I could think of to make it fail, and it wouldn't. I even marked my PIEces so that I wouldn't get yours confused with mine.

I'm beginning to believe in magic!

Oh well, at least I accomplished one thing. I got my PIE box mounted to the underside of the HU (in the space for the cassette tape or MD module) with heavy-duty mounting tape. Better than where it was.

I'm beginning to wonder if some 8s were made with MPV HUs? I don't even know if they'd be physically compatible or not -- probably not.

wait mine is 04/03 there were some changes in efficiency for creation of parts often during 2003 out at the Mazda Plant in Hiroshima (but is the HU built in Hiroshima?)

this just got really really confusing...thanks Bob for spending the time to figure this out

Got mine installed yesterday and it does work. I too assume that it is a head unit issue. Here's my logic:

On mine, it does say "EX 1" but the "1" flashes all the time. This says to me that the head unit is waiting for the CD changer to load up disc 1 (which it obviously cannot do). When I first talked to a technical contact at PIE, he told me that the module could not be used for AUX purposes because the logic chip in the PIE unit is only a translator. He said that without the CD changer connected, there is nothing to translate. What this means is that the head unit sends the Mazda command to select disc 1. The logic chip in the PIE module translates this into an Alpine command and sends it out the port. But there is no hardware (CD Changer) to receive the command and no hardware to send the Alpine "Change Successful" response back. If there was, the Alpine "Change Successful" command would be translated back to the Mazda "Change Successful" command and the "1" in "EX 1" would stop flashing.

Apparently, some head units in some of our cars are 'lazy' and just let this slide. Some other units, however, see that the CD has not changed after an amount of time and decide to cut the audio. This is a somewhat logical move to make because if the changer is malfunctioning, the audio signal it’s sending is likely to be invalid.

There are two ways to address this, but unfortunately neither is something we will be able to do ourselves. The first place it can be resolved is in the head unit logic. I have my doubts that the head unit logic can even be physically updated (the chip is probably not flashable), so the only option is to swap out the head unit. The second option is to update the microchip in the PIE unit, which does in fact seem to be flashable. The update would have to send a Mazda "Change Successful" command BEFORE the timeout occurred, even if no Alpine changer was found. The code on this chip then becomes more then merely a simple "translator".

This COULD be done, but for someone to try and start from scratch would be a very daunting task. With the right tools, one could probably extract the existing program off the chip in assembly. With that in hand and enough understanding of the protocols, the program could be modified and the chip re-flashed. But the only person I know that remotely has enough knowledge to do this is OverLOAD, and I doubt he would take the time to do it. Not because he wouldn't want to help but because not only would he not profit from it, he would also be helping a competing product.

If someone else wanted to attempt this, I think it would be somewhat straight forward (for someone that understands assembly and microcode). Since the program on the chip is a simple translator, I would expect there to be two lookup tables. The first table would hold a list of commands that come in from the head unit and the respective Alpine command to send back out. The second table would be the list of responses coming from the Alpine changer and the associated Mazda response to send back to the head unit. Any commands and responses that are not needed would be ignored and therefore this list would be fairly short. In fact, I would venture to guess that there are probably only 3 or 4 entries in the response table (one of them being the “Change Successful” command I mentioned about earlier).

As you can tell, I’ve dabbled in this stuff but I am by no means an expert. It is my opinion that this is completely within the realm of possibility for PIE to fix. I would also guess that the have already fixed it and are getting ready to release a version dedicated to AUX input. This would probably be a different beast however: it wouldn’t be a translator like the current module but instead simply a protocol “faker” that looks only for “Change to Disc 1” and responds with “Change successful”. I think it would be extremely simple for them to do and I would guess it’s on its way.

We could compare serial numbers, model numbers, manufacture plant information, etc. of our head units to prove it’s the head unit. But I suspected it was from the moment I plugged mine in --- even before I read that thews module worked for bob.

This is unfortunate guys and very frustrating to have some of the knowledge but not enough to help. I’m very sorry for those of you that it doesn’t work for. It’s even more unfortunate that you may be past your return date. If you’re not, I strongly suggest you return it and see what comes from PIE. Our other option is to contact PIE and ask them if they are working on an AUX module and if it would be possible to get our current module reprogrammed with that code (assuming such a thing exists). But I don’t have high hopes for them cooperating in that way.

Best of luck to all,

eXe

...Apparently, some head units in some of our cars are 'lazy' and just let this slide. Some other units, however, see that the CD has not changed after an amount of time and decide to cut the audio...

I wonder if it's possible that there is a setting that can be changed on the head unit for this. You know how some stock stereos would spit a cassette adapter out because it fails the test to see if the tape is intact, but you could push a combination of buttons to defeat that test, and you'd be able to use the cassette adapter? While this is a little different, I wonder if there's something available in a "hidden" code, similar to what some do to cause the NAV software to puke?

Exe.. what build is your 8..
and you are right about PIE.. They told me they are working on an RX8 only unit. but did not have any idea when we would see it..

MY next step is going to be sending input to the HU directly. if that does not work.. then I will do the CD input mod.


Hey bob.. again i am sure you did this.. but you did power your HU down before each install? (disconnect the Power to the HU ? or Battery..)

Also it looks like you and i have almost the same damn car. Build date and all :) ....

and are you shipping that back today ? be sure to use my label I sent along. its prepaid.

Damn Mazda so far the HU has me for almost 400 extra research bucks..

Come on Mazda Throw us a Bone here

Our other option is to contact PIE and ask them if they are working on an AUX module and if it would be possible to get our current module reprogrammed with that code (assuming such a thing exists).
I already did that and was told that yes, they are working on a unit that will do AUX-IN for the RX-8. They are aware of the potential market. Alas, the tech.support guy I talked to had no ETA for this RX-8 specific unit. It will be at least a couple months, according to him.
He also said that they will not provide a fix or reflash to the current MAZ/PC-ALP adapters - if they come out with a solution, it will be a separate unit.

Echo echo ........... :)

Sorry if I posted something that was already speculated. I tried to go back several pages and make sure I wasn't re-posting something that was known already.

thew, how can I tell what build my car is? I have never looked for it. Is it near the VIN? I know it was one of the early ones.

just trying to save u the headache.. look in your drivers side door jamb. theres a plate with all the info. Build date, paint code, Vin number.....

In the meantime, I'm going to try and consolidate some of the good/no-good information here. Please reply with information that is missing from this list, and if you have tried this mod, please reply with the information here.

This information has been transferred to the first post on the first page of this thread.

Hey bob.. again i am sure you did this.. but you did power your HU down before each install? (disconnect the Power to the HU ? or Battery..)Not the first time. I just plugged it in and turned the key and it worked. When I pulled the mp3 unit I had the whole HU removed, so it was powered down completely at that time.


Also it looks like you and i have almost the same damn car. Build date and all :) ....Yeah, except yours has a few more appearance mods.

and are you shipping that back today ? be sure to use my label I sent along. its prepaid.Yes, I am going to the UPS office at ONT in an hour or so. I assume that you have the tracking #, but in case you don't, send me a PM.

Damn Mazda so far the HU has me for almost 400 extra research bucks..

Come on Mazda Throw us a Bone hereNo sh*t! Mazda has the input already engineered, they just won't sell it to us!

I'm installing mine tonight. Pray to the deus ex machina for me.

good luck :)

That thing looks exactly like the PIE MAZ/PC-ALP adapter. Even the description is similar.
So much so, that I think this is nothing else than that - sans the label on the box.

yea that looks like a copy of the PIE.. maybe theres works better..

it may have the signal that some of the other people were missing.

Ahh crap, i threw all the packaging away :( I got it at a local place in Utah called Car Concepts who ordered it in direct from PIE. I'll see if I can get the part numbers from the receipt.

I was looking at the http://www.pie.net/pcmazda.htm

and noticed the pioneer unit with XM satelite radio interface. Anyone try this unit because all I see mentioned was the Alpine unit, any ideas?

I did a Yahoo search and came up with the address: Car Concepts (801) 467-0475 3405 S State St Salt ... UT

Is that the place? If so, I'll give them a call and see if they mail order. Just to confirm, your setup is: bose, single cd changer, and no nav.

At this point, I'm willing to roll the dice. I was ready to try the cd player hack, but this looks easier, if it works.

Yeah thats the one. They said PIE was backordered on new units but because they sold one to me without telling me that, PIE was kind enough to rush them the first unit of the newest build. And yeah thats the setup I have. Bose, Single CD and no nav.

Just out of curiosity, have people ruled out the possibility of a bad PIE unit or alpine y adapter? I haven't read the whole thread, but it seems like its certainly a possibility. Hope it works out for you!

Hope it works out for you!Go back to post #220 in this thread (page 15) and see what I tried. The only significant difference in Thew's 8 and mine is that my HU is probably newer, since it was replaced after the dealer fried it.

the saga continues.. I still have yet to try my pie again after telling the Nav to turn on the Serial port..

i doubt it will help ..

we shall see.

Project,

Ok, just one last thing before I order and take a chance: you are also using the rca adapter, right? Also, what external devices are you running through to the HU, Ipod, rio, xm, etc. that work?

Chalk up one more for those who got the PIE MAZ/PC-ALP to work! :cool:

I played music for a good 5 minutes from my Archos MP3 player using the PIE aux-in solution and had no cut-out... so I can safely say it works in my car.

I have the non-Bose stereo, single CD, no navigation system. It seems that this combination so far worked for all who tried.

Some comments about taking apart the interior:

be careful when removing the first trim piece (from the armrest to the ashtray). Right next to the back of the handbrake lever, there is a fastener that is not the regular push-pin but rather a plastic hook. You need to push that in with a flathead screwdriver from the passenger side otherwise if you just pull the panel, it will break. I need to fix mine now (grrrrr...). Not a big deal but still, it's better to avoid breaking anything. All the other fasteners of this panel are just pushpins.
contrary to l008com's otherwise excellent iPod install instructions (http://www.whatsmyip.org/ipodrx8/), I did not remove the whole ashtray light assembly. The darn thing wouldn't want to budge... so I detached the bulb instead.
the 10 mm bastard bolt is the dumbest idea I have seen for a long time as far as disassembly goes. Still, I think it does serve some purpose... primarily it makes stealing the radio rather complicated in case you don't know about it, and also, it probably keeps the whole unit stay in place rather well. It is pretty heavy, and this will prevent it from moving and making noises/rattles. The plastic pushpins are not too strong. I decided to place the bolt back where it was.
I also had to remove a small metal bracket under the steering wheel (after popping out the plastic trim bit) to gain access to that bolt - otherwise there's just too little room. It's held only by two screws, so might as well take it out instead of trying to work around it...
taking out the radio is a royal pain in the ass. Those plugs are hard to get out. Plus, my cables were so short that I even had to pop out the vent above the unit so that I could squeeze my hand behind the radio to unplug everything. Then it turned out that they electrical taped the cable harnesses together and that's what made them so short. Needless to say, I cut that blue tape so I can work easier.

Here are some markings / numbers from the audio assembly in case someone can compare with theirs - perhaps there is a difference that will explain why it works for some and not for the others:

Outer housing:

FE01 66 DSXA 14789521
SERIAL NO: 03H1B50076

Base (sticker visible after removing the CD unit):

FMS Audio Sdn.Bhd.
Model No. 14789520
B-No. FE01 66 AS0/14789810
Serial# 03H1B50054

Maybe some of you can compare yours and see if there is a discrepancy (other than the serial numbers of course :D).

Now I'm contemplating where should I mount the PIE box... I'm thinking I'll put it under the radio, where the MD or tape player would go. Just have to fasten it somehow - maybe with velcro, but I'm concerned about the sticky sides detaching due to heat or something...

Good news indeed! What's your build date?

Actually you can just leave everything connected if you are careful. If you leave the shifter knob on, it will prevent the threaded shifter shaft from gouging the black lacquer panel.

Agreed, but I believe there are four screws holding it in place.

I mounted it with some heavy-duty all-weather mounting tape that I got from Home Depot. Seems to work.
