Garmin GPS 48 - Manual (Page 45)

Route Navigation
The last form of navigating to a destination with
the GPS 48 is by creating a user-defined route. The
route navigation 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 possible 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
segments called “legs”. The waypoint you are going to
in a leg is called the “active to” waypoint and the way-
point immediately 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 48, 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.
