Replacing standard head unit with an aftermarket one question
I have a quick question I'm sure you will be able to answer.
I have a new A3 arriving in the new year, and have had thoughts of replacing the standard concert CD player with an aftermarket double DIN Sat Nav unit.
All I want to know is:
1, Will I need an adapter place for the facia? will a standard double DIN be a straight swap for the concert unit?
2, Will an aftermarket unit cause any problems system wise? i.e. will I need to get fault codes removed or systems re-programmed?
