I've had it for two days now and just noticed that when using the toggle on the Nav control to move around on the map screen, it won't allow me to go downward (i.e. behind the vehicle), only forward and to the left and right? There's got to be something wrong, correct??? Or does it not allow you to toggle the map screen in that direction?

EDIT: I guess it's really a joystick, not a toggle

I am able to move in all directions with my nav joystick, yours must be malfunctioning. Time to use that warranty!

Sometimes you might have to wait a second or two, then you should be able to move in any direction.
