Had a problem for quite some time with my stereo. i have an 03 A4 1.8TQM with bose. The stereo works sometimes and not others. The unit never loses power but the sound will just go away. sometimes its intermittent and other times it wont work for days. Dealer says there is a short in the head unit. Question is where can i pick up a replacement? or any suggestions for a replacement?

email me.
