I thought that I would touch base with everyone who is intersted in either product. I've tried out Sirius & was not impressed with the service or the quality. For example I live in Phoenix,Az. & the reception here is terrible. Everytime I go under the overpasses it shuts out for about 3 secs. then comes back it's an on going battle with this. Not impressed with this ,you spend a monthly fee for this it should be Flawless.

Now I own XM I love it. I have no problems with it & the customer service is outstanding!!! I'll never go back!!!

I hope this help out for you!!!
