Most dealers get it turned on for 90 days (IIRC, something like that) so the sat radio will work while the vehicle's on the lot. Once someone buys it, the dealer is supposed to notify Sirius to start the 1-year subscription. Some get slack, and forget, and the buyer's Sirius gets turned off after 90 days (or whatever)...
There's a thread about this happening to a few peeps here on the forum, somewhere.
But yes, it's up to the dealer to submit your info to Sirius.
