exactley thats why i want it plus i go on trips like backpacking, mtn. biking so forth so long trips is what i do. so instead of having to search for a good channel to listen to i know what i want to listen to and just change it to that type of music. i do occasionally have my cd's which right now i have my fosgate loaded with all 6 slots but i do mostly listen to xm. and you dont lose the signal anywhere i been in the middle of the mtns and still get reception because its satilite which is cool so while im relaxing after a hard ride or climb or trek through the mtns i listen to some music with my buds. plus to clear why i went xm then sirrus is that xm has the portable unit the delphi system which i have 2 of the 3 the boom box and my car system so i thought that was cool i can just pay one charge and be able to listen to it at home or in the car. didnt think this was going to get so many responses in this thread but thanks i like the info that who helped me and its cool. hope to cya on the road.
