I definitely want satellite radio. In LA, there are absolutely no open radio stations, so it is very, very hard to use my FM transmitter for my ipod. All of the radio stations are 70% Mexican (why would anyone need that many????), 20% rap/hip-hop, and 10% annoying sound clips, annoying hosts talking about some stupid middle school boys locker room subject, and a dash of the same songs played over and over again. We had a really good classical station, but they took that off.
Oh and satellite radio antennae do not go on the roof. They are mounted inside the windshield, usually around the mirror.
