Yes, it is the same as the xm in your truck. Directv has some of the xm channels available, but not all. The big band channel (channel 4 on xm) is on directv channel 801.
I commute about an hour each way to work in a rural part of Texas and I would sure hate to give up my xm radio! No static, virtually no commercials, and a LOT of musical (and talk) choices.
