My A$ came with Sirus radio but I would like to change it to xm. Does anyone know if I can just use a standard xm module or do I have to go through the dealer. The dealer wants something like $800 for the module but I can buy a standard xm module for $99 that plugs any aftermarket xm ready tuner.

 

SIRIUS is so much better than XM!!!

...but I am just a Howard Stern fan.

 

Why would you want XM over Sirius.
Do you think less is more?

 

I have both XM and Sirius (got XM first) and I think Sirius has MUCH better programming. If you haven't had satellite before, or only XM, listen to Sirius a while before deciding.
