4.4 Registering Routes
Often a trip from one place to another involves
several course changes, requiring a series of
route points which you navigate to, one after
another. The sequence of waypoints leading
to the ultimate destination is called a route.
The GP-80 can automatically advance to the
next waypoint on a route, so you do not have
to change the destination waypoint repeatedly.
The GP-80 can store 30 routes and each route
may contain up to 30 waypoints. Routes can
be registered while in the Plotter 1 or Plotter
2 display mode.
Registering routes
1) Press the [WPT/RTE] key.
2) Press [5] to select Route Planning. The
route list appears.
Figure 4-14 Route list

The route planning/waypoint list window
appear as shown in Figure 4-15. The
waypoint list window lists the position and
data for each registered waypoint. No po-
sition or data appears for empty
waypoints.
