Sirius does have some commercials on stations like the comedy and news stations.
All the music stations that I listen to don't really have any commercials.
The songs aren't played over and over again. I very rarely hear the same some in a 10 hour time period.
Since XM and Sirius has merged, the stations are a little screwy. They still havn't put everything together.
I have both XM and Sirius. Can't get Shade 45 on my XM but I can still get it on my Sirius.
The reception is phenomenol. I can get stations when I am in the middle of no where in the mountains.
Since I installed the set up, I have gotten docks for several of my cars. I can't live without it.
I got a dock for work and for my home. Matter of a fact, I purchased a set up for my Dad and my Mom, and my Wife. The second subscription is only 6 bucks a month, so when your wife decides she likes it, it won't cost you much to get her one.
The satellite systems are well worth the money!! And I do mean WELL worth the money.
The MP3 player of Ipod on the FM transmitter works fine also, you just don't have hundreds of channels to scan through when you are tired of listening to your own music. And you have to download your own music on the MP3 and the IPOD.
I use all these systems as I am kind of a music junkie.
