Just got a few questions.
I have just bought a new headunit for my 2004 A3 2.0Tdi Sport after my last one gave up the ghost.
On the OEM headunit there are 3 ISO type plugs, 2 of them go straight into the new wiring harness of the headunit, but
1. When I remove the key from the ignition the headunit stays on, the Audi one switches off. Do I need to find a switched ignition supply and if so where and what colour of wire should I be looking for.
2. The dimmer function doesn't work, again I guess I need to find a wire that the headunit can use for this, so where to look and what colour of wire should I be looking for.
3. The rear speakers don't work. I guess from reading other posts that this is due to Audi using an amp to power the rear speakers. So should I re-wire the rear speakers or find the wire for the rear speakers on the 3rd ISO type plug? If I re-wire how to I get at the rear speakers ? If I use the exisiting wires what are the colours for them.
Any help most appreciated
