Hi everyone, Trying to solve an issue; The first day i bought my car , i replaced the "Audi Concert" to RNS-E (2nd Gen) , but from day 1 the Aux - in is not working. On menu i can see Aux in , although it wont deliver any sound whatsoever.. I checked the wire diagram of Concert and RNS-E , they seem to be identical so i thought it should work properly unless there is a damage on the aux cable. But since it was originally there , i dont think this is the case. Should i activate anything on VAGCOM? Because i see no point in this as i already have aux option in Source menu Should i manually wire anything to make it work?
