Sirius 6 Months Free Trial - How?

[SeCX-9]

Hi,

Just picked up an 09 CX-7 AWD for the wife today. There is a Sirius radio and documentation but nothing on how to get 6 months free? When I got to the Sirius site, I am asked for a coupon and to pick a billing plan.

Is there some coupon code you got with your car? I didn't receive anything from my dealer other than the guide and the Sirius Serial #s, but nothing that gives me a code to enter ont he Sirius site.

Thanks
Howard
