Hi, I am seriously thinking about going out and buying XM. I have a question first though. I was interested in getting the Sony add on receiver. The one with the permanent install, not the one that includes the cassette adapter. My question is once I install this can I take this receiver out and us it in a different car if I purchase a cassette adapter. And can I use this receiver inside on my stereo? Basically I want it to be permanently installed in my car but wish to have the ability to move it to different cars and inside the house. Also I was curious is KIIS-FM out of LA the actual radio station or is it just another satellite station programmed like KIIS-FM? Thanks!
