We had it for a while when I got the Lincoln...but it's kind of like listening to a radio station without any commercials which is good...but still listening to what they want to play.
Yeah, I hear ya on the what they want to play part, but for me, because I Move around so much I can't always get radio reception, at least what I want to listen to.
I also carry about 100 CD's with me and my MP3 player so having music isn't an issue. I like the Sirius because I get the rock stations, some talk radio that I like and weather at the push of a button for different areas I'm in.
