My friend has it. Its such a great service, commercial free radio 24/7. One of its best features is you don't loose a station when you travel state to state. You can listen to the same station from Michigan to Florida. Your not stuck listening to some off the wall station.
That has to be one of the worst things about traveling, allot of stations play rap, pop, country, rock all on the same station LOL. I have been thinking about becoming a XM Satellite radio subscriber. How much is it per month?
