I think there is some sort of communication between the Dealer and Sirius about when the car is bought. When I got mine I didnt have to do anything to activate it, it just worked. Then a few weeks later I got a welcome letter from Sirius. So even if the previous buyer didnt use it it was probably activated for the 6 month trial anyway. If you want to activate it, call them and if you complain that pricing is too high they will usually give you a deal. Then when that deal runs out call them again and they will give you a new deal..What about day I buy the car used and the original buyer never activated?
You can get the ID code on channel 0. Log into Sirius site with that. It will say when it runs out.I bought the car a few months ago and have only done short trips, so I never used it. I did not knowingly activate it by going online etc.. I was expecting something in the mail welcoming me. I was thinking I still have the 6 months, but maybe not. How do you normally sign up for it? Does the dealership give them all my contact information? I have to look into it. Thanks.
