A CD got jammed in my deck and pretty much toast it.

I'm looking for a Symphony II deck for my 2002 A6.


Also, does anyone know what the BOSE line to and from the deck is for?

thanks

Email me if you're interested. I took mine out of a 2003 A6 at 18K miles and replaced it with a RNS-E.

...the Bose amp wants an unprocessed signal.

The HU sends a processed, EQd signal to non-Bose systems, where that pin is floating, and the output changes to flat once that pin is grounded.

Thanks for the info!

And in newer system the Bose pin only disables the internal amp for the front speakers. The coding makes it output Bose or flat signals.

I've taken 2006 Audi radios and changed the Bose setting with a VAG COM and tested the output response with pink noise and an RTA< and the damn thing does not change until you ground that pin.

Look at the wiring diagrams for Bose and non-Bose cars.

And on CAN cars I've seen a GALA or GA pin which is tied to ground only on Bose cars per the wiring diagrams. I assume that on CAN cars the VSS wire is on the bus, and that the GA designation is no longer accurate.

just make sure you get a part# starts with 4B0 for the Sym II
