There is no sirus or xm anymore. Yea you can spend money converting your car to sirus. But xm was purchased by sirus a like a week ago and the stations are all going to be merged in the summer. Also i've never been charged anything for xm how can they charge you if they dont have your credit card number???? you must have givin them your credit number cause they dont have it. If you go with xm you might get a discount. Might not anymore cause i dont think sirus gives em and xm = sirus now. It doesnt matter what you choose. Go with the cheaper one.
