Couple of questions, and i'm sure they've been answered already, but:

1) Font size in the Display bar, how do i make it bigger? Its too small to read safely while driving.

2) How to stop the postion indicator and compass, etc from being so 'fidgety' (jumping around) when not moving. Looks like Godzilla is playing basketball with the car at every red light!

3) I prefer imperial units over metric. How do i change that in the display? In fact is there a universal setting for imperial/metric for the whole of the NIT?

4) Auto-centering. Is there a shortcut to turn this on/off? I like to scroll around the map to see whats coming up (especially when out hiking and using satellite maps), but then i have to go back through the menu to get autocentering back on. PITA.

Thanks.
