I installed XM in my car a few weeks ago, everything seemed fine. Last weekend I took my first extended trip (Phila - DC) and I had a signal only about a third of the time. The rest of the time it was either very distorted or I simply got "No Signal" on the receiver. My first (and only) thought was maybe I crimped a wire and high speed was the last straw; but no, since I've been back in town it's been perfect - nary a dropout. Any ideas for troubleshooting? I'm really depressed about this. I was so pumped for the trip I didn't bring any other music. So I was left searching the dial and came up with junk. I have to go back down tomorrow - so bonus points for a magic miracle fix!
