Overlay Data
On any Page display except Satellite Status, you can 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 display 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.
The various data available from your unit are divided into categories in
the Overlay Data menu. These categories include GPS Data, Naviga-
tion, Trip Calculator, Time, Sonar Data and Miscellaneous Data.
You can select items from any of these categories for display, in any
combination — the category divisions are there only to help you sort
through the information.
