Title: I Don't Quite Understand This Thing...
Review: I bought this with the car mount kit, so I could have XM in the car and wherever else I go. Figured, wow! This is a GREAT idea, all I have to do is buy a compatible portable device (because they say that in their advertisement) and no more dismounting a portable unit from my car and snapping it into a boombox. Now, all I'll have to do is plug in this card right? Wrong! Where are the compatible portable devices as advertised? Maybe I'm missing something here... Please correct me if I'm wrong. However, If I'm not wrong, then don't buy this if your looking for something to move from the car to a boombox because the technology isn't there!
