This maybe a coincidence. But it seems that when I do an XM/Sirius upgrade or change to the program format to some other packages..The Infotainment system complete shuts down and off and then reboots in about 10 seconds and then all is normal again. The last time I changed something with my XM programming. The next day the system did this (also the last time and the times before that)..I never put the two together until I recalled this last time I changed my XM package and the next day the reboot occurred. I could be all wrong, but it seems fine with no issues until I do a XM program change.
