From my research (wire diagrams and web) Symphony radios have power on several pins.

Connector III (T8f) pin 7 +12 Con from fuse box (Red/Yellow wire)
Connector III (T8f) pin 4 +12 ACC from fuse box (Black/Red wire -- maybe Symphony I only)
Connector IV (T10z) pin 2 +12 ACC from fuse box (Black/Red wire)

There are others labeled +12 but i think they are outputs to CD changers and the like.

As I have a 2000 A6 2.7t with a Symphony I, w/Bose, yours maybe different. Check the sticker on your radio, sometimes they have pin-outs.

Is there anything wrong with your Symphony? Do you want to sell it?
If so, What type is it? (I, II, II+ or III) What features does it have? (Changer, Sat buttons, mp3 capable ect.)

I am looking to replace a broken Sym1 with a newer stock type unit.
