Hi,
a while ago I asked similar question but this time I spent some time with it and took couple of photos. And prepared myself better for asking questions.
First of all I have
S6FL USB/audio interface which should provide me working USB + AUX, right?
My car was built (after vin check) on
11.2007 and I have located the
TCU unit in the trunk with one optical loop on the side which after disconnecting is turning of the audio in radio, so I think it was responsible for this to work.
I checked fuses in glovebox, nothing is blown. I replaced the usb/aux unit in armrest. I checked cables (looking allright).
Unfortunately my Usb+aux in armrest is not powered. I have Y cable and my phone is not charging (but is recognizing the cable). After switching to aux I have set it to max volume, also set max volume on the phone, but no result. The phone is iphone X, I tested it with 8 and 5s aswell but nothing seems to be working.
On first photo I have made three circles:
- it is radio (without it connected there is no sound)
- it looks like two fibres disconnected (no red light in any of them)
- it was disconnected hidden in package with other cables (don't know what is this responsible for?)
Above left back mudguard I have unit (read about it, looking like AMP) but I don't know really how to get it out, didn't find any instructional video etc. and I don't really want to break anything.
Thanks for any responses.
