Peter,
In that your RS2 has the original wires to your ISO connectors I wondered if you could tell me which coloured wire is the illumination one, going to pin 6?
The wiring on my RS2 has been butchered in the past when someone stole the radio about 5yrs ago. According to the paperwork I have it was then rewired by Scotts Audi when the fitted the head unit that was in the car when I purchased it. Although they refitted the correct ISO connectors, they did not fit the illumination wire, so I wondered which colour wire it was from the original loom? Looking at it I am surpised how thin the wires in the original loom are and can see why some people take a power supply back to the fusebox if they are into ICE. In the original loom wiring the wires are red (permanant 12V), brown (battery -ve), white (control +ve for aerial) and then there is a grey and blue wire which I guess is illumination, but could you confirm that please, or tell me otherwise.
In fact the wiring repair that was done by Scotts is generally pretty poor, so I am planning to redo it all anyway. Interestingly they had spliced a wire to connect pin 7 (battery +ve) to pin 4 which overcomes the problems that you were experiencing. At least it does work!
I have been toying with the idea of fitting an Audi Chorus 2 headunit, but that requires the use of an amp as it only has pre-outs for the rear speakers. Also I would have to adjust the unit slightly - it is 22cm wide, where as the maximum width of the centre console is 21cm
Anyway the original RS2 wiring should go something like this:
What I want to acheive is the factory fit look and I picked up the Audi head unit off my brother for nothing who upgraded the system in his wife's A2. My other option is to fit a VW Gamma unit which I also have knocking around the garage, this has nice red illumination on all the buttons, with just the display being blue.
The connections for the Gamma unit on connector III is pin 1 Gala (speed sensor), pin 2 MUTE, pin 3 K-Bus (to ECU to remember code when battery disconnected), pin 4 switched positive, pin 5 control +ve for aerial, pin 6 illumination, pin 7 battery +ve, pin 8 battery -ve.
