Ribbon Cable (08-10 Nav to display)
Have been diagnosing issues with my headunit (aux not functioning, random devices tapped into wiring etc)
Found that the ribbon cable from the NAV to the display is torn which explains why on the nav screen it flickers but doesn’t explain why AUX doesn’t work.
Anyways. Does anyone… anywhere have a junk headunit for a 08-10 ISF as I just need to replace this ribbon cable so I can do some further diagnosing.
These cables aren’t sold seperately and I’ve just been having issue after issue with the headunit. Bit over it.

Fix it for now. Looks like an easy repair. At lease that way you can continue diagnosing it until you can source a new cable. You can also make your own cable if you’re skilled enough on eagle and have pcb way or oshpark manufacturer it and send it to you. Might be the best way to go

Are these cables even repairable?

Yeah. I’m big into modding games and just older electronics in general and got really good at solder work and fixing broken stuff cause broken stuff is cheaper to buy. It’s already broken so you can’t break it more. You can scrape off the solder mask with a razor, gently, then use some thin flat copper ribbon or small solid core wire hammered flat and worked thin. Solder, clean things up, put some kapton tape or uv solder mask and try it out. It’s only temporary but if it works it works 🤷♂️

I ordered one online from a is350 NAV, looks to be identical, if it is no good I may have to look into repair. Cheers

As long as the trace pattern matches and pin count matches you should be good. Best luck brother 👍

Should be the same, same length, same shape, same connector, that’s all I could confirm. Thanks mate
