I have a 2006 A4 Cab with the Concert head unit, Bose upgrade, steering wheel controls and audi bluetooth phone prep. I currently ise the CDC input for my iPOD.
I would like to upgrade the head unit to one with DAB. Has anybody tried upgrading and is it possible to integrate it with the phone kit (from what I can see of the wiring the Audi bluetooth system just mutes the stereo and has an audio input so the phone comes out over the speakers).
It seems possible to get wiring adapter kits for most head units so that the steering wheel buttons still work, but is there anything else i should be wary of?
One good thing - DAB units tend to come with their own antenna which looks to be easy to route to the top of the windscreen.
What I am after is a new headunit that still looks as OEM as possible. Any suggestions gratefully received.
