I got my '07 in November, used - the previous owner had it for three months. The (Chevy) dealer I bought it from wasn't clear on what options were on the car. (MyColor was a nice surprise.)
Yesterday I was trying to change the clock time (I fix servers for a living, you'd think I could handle it, but nooOOooo...

) and somewhere along the way hit the aux button and was surprised to realize I was listening to a Sirius channel. I knew the Shaker1000 had Sirius internally, but didn't realize a subscription had been activated.
Does anyone know if Ford automatically gives a Sirius "trial subscription" (and if so, how many months it is), or if not how I'd go about finding out how much time remains of the former owner's subscription?
