Route Navigation
The last form of navigating to a destination with the
GPS 12 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 particu-
lar destination (e.g., through a body of water or impass-
able 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 12, 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.
