Can a A6 unit be used to replace an A3 unit?
I know its to big, but if it could be trimmed down a bit would it work?
Potential Issues other than size, would be whether the unit needs to know its fitted in an A3 not the A6 and changing between Bose/non bose?
can these parameters be altered with VAGCOM?
Reason for this is i've been offered an A6 version for free and the one fitted in car has seen better days
Thanks in advance
