Satellite Radio - XM, Sirius?
I have experience with both. I have XM on the boat and Sirius in the car. The sound and reception is great on both. The choice really is between programming. Sirius costs a little more than XM though. I prefer XM because of their programming choices. This is personal preference. Check both of their web sites and decide which channel line up you like. There really isn''t much of a difference otherwise.
