This started happening this morning. I have the Audi Symphony II in a 2002 A6.

It just turns off intermittently. It will play for 30 seconds, then turn back on. Almost seems like it is losing a ground. I check the fuse and it isnt that. Any ideas... I am about ready to get a honda or toyota with all these damn electrical issues..[:'(]

 

It either the connection at the back of the radio or the radio itself. Find someone with the radio removal keys and pull that terd out of there and check the connectors. If they are ok go ahead and order a re-manned unit from the dealer for like $300, they also give you a core if you give them your old one.
