I saw an ad for the new XM Snap (& Sirius SV6). Seems like an interesting concept. Plugs right into the car's 12V adapter plug, had a short stem with the unit on it & plays via the car's FM radio. From what I can tell, it seems to play through your FM radio through some sort of similar "power connect" method. At least that is my thinking based on what I have seen, Is this about right for how it operates? I'm assuming you still need to attach & run an antenna of some kind. Or is the antenna maybe self-contained as well? Seems like a real basic unit. Even more so then my Stratus 6.
