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.

 

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...

 

same set up (with Nav).. same results

 

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)

 

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!!

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.

 

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.

 

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. ~~~!
