You have a 6 month Sirius trial, but will need to get your car receiver's ID and create/log into Sirius to register the unit. The steps are in the Sirius brochure in your car's book kit.
Once registered you can activate more channels/services that will all expire at the end of your 6 mo trial, including all the traffic info.
The trial began when you purchased the car, I think the Ford tech team at the dealership activate the radio when they set up tech or phone(?)
Any add on items will expire when the 6 mo trial is finished based on the 1st day of activation, so all the features consolidate to a single termination date. Its not bad since in your Sirius account, everything is nice and organized and finishes at the same time. You can continue your subscription or activate other radios, add web radio, whatever you want, you are not tied to the cars Sirius-once you are logged in and decide you would like to subscribe, its pretty flexible. ...oh and MLB just started...
-just received a flyer from SiriusXM-anything including web radio is free for trial period. nice!
