I have serious and I love it. Had it for about 7-8 months now. There are absolutely no commercials on the music channels of SIRIUS. You are going to get commercials on the talk streams, as they are basically just audio feeds of the channels they come from. I think SIRIUS has a good selection of stations. I never listen to my cd player anymore and I have a 6 disc in dash changer. If you have a Kenwood headunit you should go with SIRIUS. SIRIUS allows you to pay monthly, quarterly, bi-yearly, annually, etc. Also if you go with SIRIUS for your car, you may as well get the Kenwood Here2There since you can get the second subscription cheaper.

 

I had my antenna installed..but not on the roof of my car because they couldn't center it and it would have looked hella tacky, so I got mine installed on the right upper corner of my dash up against the windshield. You can hardly tell it's there..and with the new antennas they're coming out with they are even smaller then the one that I have. one friend of mine installed his in the back of his car next to his speakers, like under the back windshield of his camaro..and another one of my friends installed his on the outside of his excursion, you can't even see it, and he hasn't had any problems with leaks or anything since he's had it which has been for over a yr. h:
