Thinking of replacing my Concert II and 6 CD Changer for something a little more up to date.... iPod connection, bluetooth, etc... What cables, face plates, etc would I need to buy to do this properly? I have the standard Bose setup in my 3 door A3. Also can anyone recomend any good stereos which dont look out of place in an Audi (i.e. Red or Amber buttons)? Are there any websites which youd recomend for good service and parts?
