    Hi,
    Just a quick question that has been prompted by me talking to someone with the same car as me who also has Bose, who reckons it's the best sound ever.
    I've had my car (56 plate A4 Avant S Line with Bose) for two and a half years. Before I got it, it had had an RNS-E unit fitted at some point. (still got red DIS, although it wasn't coded for Nav when I got the car. S8Craig sorted that for me.)
    I've never had any problems at all with the sound system, but I've always felt the sound was utterly average.
    I've read a couple of times that when you fit one of these units to a Bose car, you need to swap a wire or two on the wiring harness to make it sound great. Would this make a huge difference to the sound, and how can I tell if it has been done? I have no problem removing the unit by the way to look! Just don't know what I'm looking for!!!
    Sorry to drag this subject up again, but I can't find the answer.

    Thanks in advance,

    MMM

    S8craig would have told you at the time if the harness was incorrect as the BOSE pin error would have been showing. On a 2006 if the wires had not been moved then it would not be codeable as the K-line has to be moved to where the BOSE line would have been and the BOSE wire is then relocated to another empty slot.

    The sound in Avants has always been pants for BOSE, the cabin space is just too big. I've owned 9 Audis always the BOSE avants have been fairly pants compared to the tight cabin sound of a saloon. my S8 had BOSE and it was great, the RS6 avant that followed with BOSE was awful. The W12 that followed was great and so was the 4.2 Tdi. The Q7 with BOSE always sounded lacking.

    PS: For some reason I feel like attending a dyno day, anyone else?
