I recently finished removing the navigation system components from my car, and I tested all the electronics with the nav stuff removed to make sure leaving the nav harness in there wouldn't effect anything else. Everything worked fine, just the ususal flashing DSC light after unplugging the battery.

Then, after reassembling everything, my front left door speakers only produce a quiet fuzzy sound. It's not a buzz, and they seem to vibrate a little throughout music, but it doesn't produce noticeable sound. I've checked the radio plugs for bent pins, etc, and I couldn't find anything problematic so I replugged everything in and still, same issue. The other electronics on that door work fine. Any ideas?

bump. I've checked to make sure that everything is plugged in, and I checked the fuse. Connectors for the head unit look fine, but what are the chances are something getting bent, connection being off, etc?

Okay, I got somewhere!

It looks like the signal for the Front Left speakers is run through the DVD unit on nav-equipped cars. I've attached the wiring diagram for that section below. The way I see, I can either just leave the DVD drive installed, or find some way to complete the connection. Looks like the speaker signal just runs from the head unit through the DVD unit and continues on it's way around and back to the front.

Hey man.. I recently removed my OEM nav system and noticed the same problem. Did replacing the OEM DVD unit fix the problem? I still have mine... Just curious. I was planning on doing some rewiring soon... let me know what you come up with! Thanks!

Hey, I was wondering if over the last year anyone has found a way that you could remove the Nav DVD Drive while keeping the Front Left speakers working. I considered cutting and splicing but didn't as I never found out exactly what would need to be spliced together. Anyone have a picture of the wiring of a non-Nav GT RX8 from down there?

Hi,

I've got the exact same problem as you. I thought it was a coincidence that 1 speaker had failed after removing the stock nav unit, but after reading this, I know now it's definately to do with removing the sat nav. I've started a thread on my problem here: https://www.rx8club.com/series-i-interior-audio-electronics-24/front-drivers-side-speaker-not-working-185945/ but as of yet had no responses.

Did you ever fix this problem? I've not got the option of reinstalling the nav unit because A - I no longer have it and B - There is a car PC in it's original location, so my only option is to splice and connect some wires which I'm quite happy to do - I just need to know which ones!

Could anyone with good knowledge of the RX8 wiring come in here?

Thanks

Can anyone upload a pinout of the 2 white connectors from the back of the stock nav unit?

I've searched on the forums but cannot find anything. I reckon that the drivers side speaker wires from the head unit pass through the nav unit where they are mixed with the nav voice then passed on to the crossover in the door. Theoretically if I connect the 'input' speaker wires directly to the 'output' speaker wires in this wiring loom, it should work.

barry_swanne

OK,

Had the multimeter out today but was unable to fugure out which wires do what so a pinout really would help. Surely someone has one that they can upload or at least point me in the right direction?

Thanks

Hey, sorry for delay; I just happened to see the reply to this now.

I never did find a way around this BUT, it's not the nav screen unit that causes the issue. It's the DVD drive under the rear center console. From what I could tell, the wiring for the front left speaker is run through the DVD drive so that when it speaks it plays through the front left speakers. Unplug the DVD drive, and those speakers don't work. So, if there would be a way to figure out which wires are for the front left speakers for both connectors on the DVD drive, I'd assume you could unplug it, cut the connectors, and then just splice those wires together.

I still have the DVD drive and aren't great with wiring though, so I hadn't gone any further because I couldn't figure out which exact wires were for the speakers. I've got the schematics though, uploaded below.

EDIT: Just saw that you're in the UK, it's probably opposite for you? If so, the wiring may be different, but this should give a general idea.

Thanks for posting this - you're a star! I'm going to study this tomorrow and hopefully get somewhere. I'll let you know how I get on.

Thanks again!

Did you have any luck with this?

On another note, does anyone have a picture of the wiring under the rear center console from a car without nav?

barry_swanne

Sorry for the delay in replying.

I've not had chance over Christmas/New year to look into this further, mainly due to the cold weather - didn't fancy pulling the interior to bits in sub-zero temperatures.

Anyway, I've started having a look today and come across something very strange and frustrating.

I've located the 2 white connectors that went into the back of the original nav unit (see diagram 2) but J3-02 (the smaller of the 2 connectors) seems to have 4 crucial wires missing; see diagram 1.

I've worked out from the PDFs in the post above that all I should need to do is connect 1N and 1M to 1O and 1P respectively; see diagram 3. I'm assuming the connections from the audio unit to 1O and 1P are line-level and just mixed with the nav output then sent on to the amp in the boot? In theory, connecting these together will resume output to the drivers side speaker...

As you can see though, my problem is that I can't find any of these connections. Hopefully it's just me being thick and someone can help.

I've also found a 3rd connection which goes into a black box (see last image). Not sure if this has anything to do with things but though I'd post anyway to give the full picture...

Has anyone tried patching the cables together to take the DVD drive out of the picture? I'm more than willing to crimp wires together to take it out, but I don't want to cut the connectors off until I'm sure it'll work.

Have you guys succeeded? i am also eager to remove the dvd drive from the car in my car pc setup

barry_swanne

I did actually get this to work. I've sold the car now but wrote down what I did somewhere I even took some pictures I think so I will try and find the details and post them here.

Basically the feed from the head unit goes through the the DVD/Sat nav unit and combines the sat nav voice with the driver's side tweeter (in my case the right tweeter) before it goes to the amplifier if you have a bose system (though I'm sure it's the same for the standard setup). So taking that DVD box out, breaks that connection.

All I did was work out which were the correct wires and soldered them togther.

As I say I'll post the details up ASAP.

Bsellmeijer

if you managed to fix that issue i would more then welcome pics and written down notes! i have a vague idea as to which wires i should connect to eachother but i am not 100% sure

thanks in advance

Barry Swanne,

Any help you could give us would be greatly appriciated.
I recently removed my nav unit and found out the left speakers were not working.
So, quick question, did you attach the wires behind the head unit or did you put jumpers where the DVD player used to be located at?
Of course doing the wire jumper at the DVD player would be so much easier so that is why I am asking.
Thanks,

barry_swanne

Hi,

As you can see from the image below (which I took at the time)it involves cutting and joing 2 wires.

There are 3 pages from the electrical diagram which I've posted here:

http://www.adigi.co.uk/dev/p92_Electrical.pdf
http://www.adigi.co.uk/dev/p94_Electrical.pdf
http://www.adigi.co.uk/dev/p96_Electrical.pdf

If you look through these you should be able to work out which wire is which, strictly speaking they should be the same colour as below but my car was a RHD so it might be different in the US.

Sorry I can't post any more specific instructions - I should've wrote them down at the time!

Thanks for posting up your results! I had kind of forgotten about this, but glad to see that you got it to work. In the next few weeks I may give it a try.

Resurrecting an old thread but the golden rule of every forum is to search right?

Well I found this thread after cleaning up my electronics this past weekend after installing a Nexus 7. I removed the Navigation DVD unit and my front left speaker stopped working. I would like to leave the unit out and just wanted to know which wires to splice.

The image above (Post 19) shows the green/yellow spliced with the purple/white and the blue/white splice with the red/black. However since the user is in the UK I am worried that this is for the UK right hand drive model.

I checked the wiring diagrams on Post 4 and the front right speakers are white/blue and yellow/red. Anyone figure out which wires to splice for the US cars? What other wire connects to the white/blue and what other wire connects to the yellow/red.

Thanks in advance for your help!

Anyone???

Can anyone tell me where that wires are because i am facing the same problem?

The wire bundle looks like it's in the center console by the rear seats. That's where the nav dvd player is.

As for the wire colors, you can find the outputs to the speaker pretty easily using a tone generator. Heck, maybe even music on your phone with an AUX cord cut and spliced. Once you know the speaker wires, I'd start pairing them with the colors shown above first. Then just start guessing. There's not that many wires back there and you're not going to hurt anything.

stel10s

do you think is in the rear center console or in the trunk where are connected to the bose amp?
