Sirius and XM Satilite radio providers both advertise commercial free radio. Both of them have commercials on 99% of their channels. As far as the service goes it is fine but it is not commercial free. Also if you do not have a tape player or AUX jack on your car you will have to use the FM transmitter. With the FM transmitter you have to find a dead channel on your radio then tune the Sat. radio to that channel and it has a lot of static and white noise, not to mention the ugly wire that has to run to your antenna.
