I'm new to Audi ownership, and i'm having a few issues changing the head unit. My car is A4 1.9tdi on a 51 plate, with a Concert Head Unit.
I'm trying to wire in a Sony BT5000, without much success, the aim is to use my phone like a good boy and also stream music direct over AD2P.
I gather the Audi wiring loom doesn't provide a switched live, so i will take one from the fuse box (I need to use it for the Molex connection for phone & pda as well).
The main issue is the rear speakers. I've tried to wire them direct last week by cutting the loom, that didn't work - so soldiered them back together and then found out about this canbus system.
So i ordered autoleads PC9-401, still no joy. I now believe my system must have Bose in it, although i have no bose markings on the speakers? I tried to look at the rear speakers, although all hidden except a sub and looks like i require the PC9-408 instead?
I've attached a link, as this is the bit that's causing the issues. Any help would be very welcome.
