you know how when the map is showing and you go to press MAP, and the menu comes up with 5 options, one of which is "Vehicle Dynamics"? well for some reason whenever i go to press that button, nothing happens. its like i just dont have that feature anymore. i had it a few weeks ago, then i had some audio work done and poof, i cant use it anymore. anyone have any idea how i can fix this?
