The GPS 45’s 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.
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’ way-
point, and the waypoint immediately behind
you is called the ‘active from’ waypoint. The line
between the ‘active to’ and the ‘active from’ way-
point is called the ‘active leg’.
When you activate a route with the GPS 45, it
will automatically select the route leg closest to
your position as the active leg. As you pass a way-
point in your route, the unit will select the next
waypoint as the ‘active to’ waypoint.
