routEs
Often a trip from one place to another involves several course
changes requiring a series of Waypoints . This sequence of
Waypoints leading you to your destination is called a route .
Your GP450X can be programmed to traverse a sequence of
Waypoints, automatically advancing to the next Waypoint as
you progress, so you do not have to repeatedly switch to the
next Waypoint . You can also travel the route in the opposite
direction, using it to return back home again .
crEatING routEs
Example route along a river
The GP450X can hold up to 50 stored routes plus one Route
Log . Each route may contain up to 30 Waypoints . If you attempt
to store more than 30 Waypoints a message will inform you that
you can no longer save additional Waypoints to that route .
A route may be constructed in one of four ways;
• from the cursor
• from the Waypoint list
• from the route list or
• storing your current position either automatically or manually.
