A little problem with my GPS system.

[Rapid Transit]

I can't select the true North pointer on the upper left corner of the screen. It's currently set as "head up", meaning you always appear as heading forward on the screen, regardless of whether you are traveling due south. I do remember pressing on the red-white diamond pointer to switch to true North, and pressing the N to switch to "head up". But now I'm stuck with "head up". Any of you guys see this problem?

Thanks,
