XM is definatly worth it. I have it installed right now.
XM has 100 channels of music (70 are commercial free) $9.99/month
Sirius has 100 channels of music (All are commercial free) $12.99/month
Sirius has 3 satilites that circle the globe in a geosincrinous(bad spelling just sound it out) orbit.
XM only has 2
Both offer CD quality sound so they both sound pretty good. It all depends on where you mount the antenna though. The roof is the best spot. Both show you the channel you are on, Name of the group, song title, and category of music.
If you want to pick it up go to A Circuit City. We do 110% price match on any local competetors. Which means if Best buy has it for $100, we will sell it to you for $90. You just need a satelite decoder box(couple hundred bucks) and a antenna (like 40 bucks). If the cd player in your car doesnt have a XM or sirius logo on it you will need a little display/controller that we can stick on your dash. Im not shure where your at, but the CC in novi has XM playing all day so you can listen to it and see if you like it. Not shure if other stores do the same thing.
