Xm radio is great if you travel a lot and are always on the road. The sound quality is not great however in a noisy car that I mostly drive it sounds just fine. The other nice thing about it is live news, sporting events like NBA, College football games and hockey games and the comedy along with the old time radio like Jack Benny and the like. They also have a ton of music channels without the commercials. I like it, I dont like the the fm transmitter they use, its super weak, I use a cassette adapter to listen thru the radio.
