My fiance has a 2007 A3 which has the factory radio/cd player installed. She'd like to be able to play music off of her iPhone. I have an A4 which has an aux input in the arm rest which does the job nicely. Is there a radio I can swap her's for that will provide the same or better? By better I guess I mean bluetooth streaming. We'd like to keep the car looking as close to factory as we can so we're not looking to buy amps/change speakers etc. Hopefully just a simple swap. She uses one of those little radio emitters sometimes and tunes her radio into that but the sound quality is pretty crap. Thanks guys.
