Hi,

you could also try to talk to the people at

http://www.group44.de (as you have a 220V, even though the BOSE is identical)

and, even more

http://www.audifans.com

The second provides English mailing lists for both the Audi V8 and the Audi 200 20V which are quite frequented. People may help you in here but unfortunately the English forum is pretty uncrowded... try to go ahead for the mailing lists!

Alternatively, try to post to the German forum in German. Help may come quicker.

Best regards

Bastian
