Hello all, I'm new to this just purchasing a 2006 CTS V yesterday. So far I love the car, it has been a real blast to drive. Question I have I could sware when initially looking at the car the previous owner messed with some buttons and on the gps screen performance tune or something along those lines was displayed. Can anyone help me out, how do I find this setting?
