check the sirius website...they have a ton of satellite radio info...hell the Delphi XM satellite radio has a wireless FM modulator that you can buy, that will make it work no matter what headunit you have. I think from what I'm pricing out...its gonna cost me like $160 in equipment and I'll end up paying the $120 for the year long subscription...not too bad at all...and I really am gonna try to mount it in the console...the backlit orange of the XM receiver will sit really well with my stock orange LCD's in the center console
XM is $160 for car adaptor and receiver unit. Then $9.99/month subscription. For hundreds of music, tv, talk, and other specialty channels, plus commercial free, clear reception, you just can't beat it! Getting mine soon!
