Creating and Navigating Routes
The last form of navigating to a destination with the
GPS 38 is by creating a user-defined route. The route navi-
gation feature lets you plan and navigate a course from one
place to another using a set of pre-defined waypoints.
Routes are often used when it’s not practical, safe or possi-
ble to navigate a direct course to a particular destination
(e.g., through a body of water or impassable terrain).
Routes are broken down and navigated in smaller seg-
ments called “legs”. The waypoint you are going to in a leg
is called the “active to” waypoint, and the waypoint imme-
diately behind you is called the “active from” waypoint. The
line between the “active to” and the “active from” waypoint
is called the “active leg”.
Whenever you activate a route with the GPS 38, it will
automatically select the route leg closest to your position as
the active leg. As you pass each waypoint in the route, the
receiver will automatically sequence and select the next
waypoint as the “active to” waypoint.
