Heading down for the Super Bowl XLV in Arlington, Texas? If you have a GM vehicle equipped with OnStar, this news is for you. Super Bowl organizers have said not to use GPS to help alleviate confusion over road closures, but rather to use the printed directions on their parking pass. However, OnStar will be offering its subscribers access to secret routes and road closures via their turn-by-turn direction service. A group of specially trained OnStar advisers will relay information during the event to help owners get to the game. The best part is that the turn-by-turn service will be free to all OnStar subscribers during the big game — and everybody likes free stuff.
