The way I read it if you have a car with Sirius, you could add sports and talk from XM and all the current Sirius programs for 16.99.
In my case I have a new car with XM and could add sports and talk from Sirius to my XM for 16.99.
Sounds great to me the best of both worlds. XM sports suck sinc losing NASCAR, except they do have exclusive baseball. Now Sirus subs can add baseball to there lineup.
For all the present cars, does the satellite radio have to be reprogramed or will it just be able to tune in both companies?
