Overlay Data

On any Page display except Satellite Status, you can "float" or overlay additional GPS or navigation data on the screen with the Overlay Data command. For example, if you left your watch at home, you could dis- play the local time on top of the map. Or, if you wanted to see details about your route and trip, you could show your bearing, course, average speed and trip distance.
