Concert III Radio Problem...
My Symphony II HU was in need of replacement, and whilst I have the RNS-E, I still need a decent replacement for the Symphony II for when the car moves on and I strip back to standard, so I managed to snatch up a cheap Concert III radio from a MY08 A3.
Because the Concert III uses the Quad-lock plug I assumed it would all be well using the cables that I use to power the RNS-E, but it doesn't seem to be.
The only thing that I can guess is that the Plug&Play plug that I have installed in my '04 car to allow the RNS-E to function is completely different to the setup of the Concert III HU, but surely if Concert III owners are able to install an RNS-E without any additional cables, then surely this should be working for me?
Hopefully I can sort this out but I need your help to help me with the plug diagram. Can anyone tell me which one represents the live feed from the battery?...
