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.

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.

Overlay Data highlighted on sonar menu (left). Overlay Data Shown

menu (right).

To overlay information on your screen:

1.Press MENU↓ to OVERLAY DATAENT.

2.If you currently have any overlay data on your screen, it will be listed here. Select (ENTER TO ADD) and press ENT. The data viewer shows information categories with "+" or "–" symbols next to each category name. A category with a "+" next to it is expandable, meaning its con- tents are hidden.

Selecting the category name and pressing ENT will show the category's contents, so you can choose items within it. An expanded category (one with a "–" next to its name) can be collapsed to hide its contents. Just select the category name and press ENT.
