Just to add to this post, I had an xm receiver I bought on amazon installed with my new F90bt last week. It is getting a select few channels (like 20 or so). Not sure if it's a demo subscription of some kind, but it is a little different in that I don't seem to be picking up every channel. I'm hoping I may be missing a setting that lets me access more of them. Weird. Anyway, just wanted to add my experience.
