My dream is to have my entire CD collection ripped onto an in dash hard drive that I could just put on random and drive 'til my heart's content. However, such devices are few, and I'm dubious about support for them. I don't like that you can't buy them in B&M stores. Basically I'm tired of the one CD at a time thing in my car. Sure I could get a CD changer, but 6 or even 12 CDs even on random is less than what I would like. It seems my best option is XM. I've looked at their station selection and the ones I would listen to most are commercial free. If they're anything like the satellite TV music stations, I think I would be pretty happy. So if anyone has XM radio, I'd love a review. Do you love it, just like it, or hate it? Any problems with how it works or with the music selection? Thanks.
