So I downloaded FORScan and was able to look at the more "detailed" error codes and they didn't really provide much more detail. It showed two faults that were satellite antenna related. Then the weird thing, today while out running errands, I randomly tried to use XM again and it worked. It worked for a about 5 minutes and then the fault came back. That happened one more time on my trip, but not it is off again.
So to me that seems like it is not a completely bad unit, and may be a connection or wiring issue. Does anyone know where the module is?
