sirius

I've been a Sirius customer for a long, long time, and when my car comes (in a week!) I'm wondering I'd I will have to switch over to the XM plan... Most of the posts seem to indicate the ct has XM, but all the brochures and press kits say"Sirius/xm".

Hi Everyone, I just got this car and I have a sirius lifetime subscription. Much to my dismay, I found out that although they are one company, I can't switch subsciptions. Is there any way to switch the wiring on it to make it compatible with Sirius without having to the tear the dashboard...
