Hi, Looking for some help from the audio experts.
In my A6 I have a double-din type 'symphony' radio system (tape, single CD, etc).

Has anyone any ideas on what I could put in the car to upgrade things a bit? I've been looking at loads of double-din systems but I'm finding it very hard to get something to match what I want, especially to match in with the reddy-orange that the C5 dash is done in.

Basically I'm looking:
Bluetooth for the phone
USB port
MP3 compatable
Is there a surround available to fit one in the car?

Not interested in sat nav or DVD or anything, although touchscreen would be nice but not vital.
