Rick hit it on the head,
After doing 28 days on the bike and almost 10000 miles I cancelled my XM account. It was worse that some of the radio stations locally, and I listened to several stations. I dont know if I'll wast my money with another Sat radio. I haven't tried the Sirius so I can't comment on that one, just dont know if I want to come off the money to buy the radio and then the setup charge to see that it's the same thing as the XM.
I think that I'll go to another MP3 player...at least the music in it will be stuff that I want to listen to.
