Here's my issue. A while back I went all out and bought a stereo with all the bells and whistles one being XM radio. The problem is, one day I turned on the stereo, and when I pushed the "source" button to get to XM, XM was no longer there. Now I'm not the brightest when it comes to the electrical side of the automotive house, so I figured I'd pose the question. Should I take the time to take the dash off and check the connections and such, or should I take it to a professional installer somewhere? I can't take it to Circuit City for them to fix since they are no longer open. Thanks.
