Hi, can someone please provide me with a colour code list for the b6 Concert radio plugs?
My radio stopped working ages ago. I have a constant 12 volts on the red/blue wire and a good earth connection on the brown, but I don’t know the colour of the accessory lead (the one that should power up when the ignition is switched on) so I can’t begin to trace the fault. Any knowledge on this one please?
I’ve just discovered that Audi don’t use an auxiliary connection but use something called a CAN-BUS. This means very little to me but I take it that’s why I can’t find an auxiliary connection on my radio connectors. Is it a relay of some kind, please?..

 

I've refreshed with an image and additional data. Any thought how to let who's connector know that is in the pic above?
