Hi, I'm after a little bit of advice please. I recently bought one of the new concert head units for my 01 A3 as the Symphony that I have in is broken. However after purchasing, I realised that the shape of the concert differs considerably to the symphony, as does the wiring. Is it at all possible to get adapters for the wires and also a facia to help the unit sit snuggly in the dash? Sorry if this seems like a daft question, bit of a novice when it comes to cars. Any help would be gratefully received.
