I just joined this site, had found it by accident. I have an 08 GXP with 1000 miles on, yes you read it right. I bought it brand new back in 08.. Here is my problem that I need help with. I took it out this past weekend for the first time this year, ran like a top, however my radio doesn't produce audio. The radio turns on fine & displays info as it should, just no audio at all. I checked the #23 fuse, checked ok. I did some research on the net & things seem point to the amplifier possibly? Any help would be appreciated. How can I narrow it down to be sure it is the amplifier?, & if that is the case, I understand it sits behind the drivers seat, behind the panel. Can anyone give me instructions on how to remove the panel & where the clips might be located? Seems like a lot of work to get to the amp if that truly is the problem. Also is the amp swappable, or does the dealer have to program the replacement one?, sorry for all the questions, just needing some help here. I would prefer to do the work myself, as I try to avoid the dealer as much as possible,as I don't want some flyby mechanic slocking up my car.. Thank you for your time.
