I'm looking to upgrade the headunit to a single din, that still has use of the steering wheel controls and potential for a subwoofer to be wired in. Attached is a picture of it, its an Audi Symphony. It is NOT the bose system (I assume so as I cant see Bose written anywhere in the car). Can someone please advise me on what I need to buy? Im looking for a nice simple single din, with bluetooth and that's it tbh.
