What's the model number for the Bose concert tape player out of the tqs? Post facelift.
Loads of decent aftermarket decks out there, depends whether you want OE look or not. For me it was more important to have a high quality sound source than factory looks and almost all factory decks sound at best ok(is).
Becker used to do some very O/E looking decks that sounded superb other than that I'd stick with Alpine or Pioneer decks.

Sell my Audi??? Kiss my rings!
The OEM stuff is usually also horrifically expensive for what your getting.
My pioneer was about 90quid, has USB, SD Card, MP3 support etc etc...
