I noticed the same thing happened to my 7 as well, I was wondering what had happened if maybe the freebie subscription got cancelled by accident.
Truth be told I don't listen to it enough to warrant taking the car to the dealer. I get such poor reception where I live it cuts in and out(from a satellite?????) - on the past 6 cars its been the same even when Sirius and xm were separate.
