Anyone here done a replacement of the signal amplifier for the radio antenna. I have a 2003 A6 Avant with miserable to no radio reception (some FM but no AM signal) and I think the signal amp is the problem. Any pointers on how to get under the headliner w/o destroying it, is the amp actually in the back by the rear hatch door?

Thanks for the assistance,

 

Did you ever find an answer to this? I have the same issue in my 02 S6 Avant
