If its within 30 days Best Buy should replace it.
I bought a Garmin there and 2 weeks later all the maps got deleted off of it somehow. I took it to a Best Buy with the receipt in Louisiana and they straight up exchanged it with no hassle. They have a 30 day guarantee.
I will own an ecoboost F150. It has a hell of a lot more power than my 07 F150 with the 4.6 in it, and Im sure it will pull my 4500lb camper a whole lot better. I cant wait for it to come out.
