As one who is going to buy a C7 soon, I'm watching this closely and hoping to hear about a resolution that makes sense. I'm a life long radio technician (both in the military and civilian sectors). Since GPS and XM are both receive only, there should be nothing about the antennas or their transmission lines that could cause this. A bad receiver connected to the XM that is leaking back out and interfering with the GPS could conceivably cause it. Anyway, ask lots of questions when you get an "answer" from the dealer to make sure they have fixed something substantive. Just my two cents...
