Im curious, can XM radio be added to stock satalite radio in my 2006, 300c instead of Sirius ?

I already have XM in Z71, Corvette and house and after having Sirius conected to 300c im positive I'd rather have XM being that I am familier with stations and Im not a big Howard Stern fan anyway :-))

Could it be possible that its as easy as cancelling my Sirius subscription and adding XM to my 300c as well ?

Thanks In advance !

PS. I LOVE THIS CAR !
