IF you have a cassette deck (yeah, I know they are going the way of the 8 track) consider an Xm Auto Cassette Adapter. Cheaper, less hassle, no static, no hassles with finding empty frequencies. It just works. I have both. I prefer the cassette. The big advantage to the Griffin is the recharging ability. For that, I will hold on to it. Of course if you live somewhere that has not filled the entire FM spectrum with jabber and cacophony, maybe the Griffin will work well (I have no way to check, living in cacophony central). And Eric's post sounds well thought out. Read that before you buy.
