I received an email from Chevrolet/OnStar: GET COMPLIMENTARY ONSTAR[SUP]®[/SUP] SERVICES* AS OUR WAY OF SAYING THANKS! My car is a 2012 I don't have OnStar and honestly not sure if it is useful for me. I guess I could activate as I have till Nov30 to do so as long as it has no "strings attached" like signing a contract. Or maybe they are just trying to introduce new OnStar services? I have seen commercials for a guy using his phone to lock his Buick...... or Maybe they are hoping I/people will be impressed with the service that I will sign up.
