XM is so, SO, much better, the channel layout, the reception, the hit's stations, all winners in my opinon, needless to say Sirius will not be renewed, I can only listen to one station, the hits station(CH1), I heard they released a new one, but I'm not sure on where that one is, not that I really care, Sirius cuts like a sprint phone.
AUX jack is in heavy use, my XM is there now. Tacky, but I manage.
