I'm looking into changing the Concert radio/cassette head unit currently installed in my 2001 (Y) A2 1.4 SE. I spoke to an Audi dealer today, and they said that the Concert 2 would be compatible (part # 8Z0057186D priced at £700!). I have been looking around this evening and found a Concert 2 for sale, and the part # is identical other than the D is replaced by FX. Does anybody know if there would be a connection issue with the 8Z0057186FX in the car? Thanks in advance.
