Had it with new car, Dropped it when couldn't justify the TCO (total cost of owenership) vs use made. Depends on your use case. If you have bluetooth, AUX-IN , or an FM transmitter, then any solid state playback device (smart phone / sansa clip) will trump SQ and playing your choice of music / audiobook / podcast vs being restricted to a playlist based "station". That said, I did enjoy my fix of BBC World Service, on the go, while it lasted. (Modern Multi Disk CD players especially those with MP3 playback, means lots of music at your fingertips for less, at a SQ of your choosing) If you do go with / keep XM, then play close attention to the Satellite radio forum on AVS http://www.avsforum.com/f/101/xm-and-sirius-satellite-radio for how to "game" the CS reps into offering you a "one time only'" renewal for $77 / year , 6 months for $25, or whatever the current special is. If you leave, they'll beg you to come back with specials. Their business model relies on inertia sales once they have you. If you have a smart phone with data plan, the marginal cost of Mog / Spotify / Pandora may be a winner, and you can use them outside of the car.
