Creating routes using existing waypoints
You can create a new route by combining existing waypoints from
the New Routes dialog.
The dialog is activated by selecting the route tab in the dialog
displayed when you select the Waypoint, Routes, and Trails tool on
the Home page. Next, select the New route option.
You can also insert existing waypoints in an existing route from the
Edit Routes dialog.
From the Edit Routes dialog, select the routepoint in the list where
you want to insert the waypoint and press the Menu/Enter key.
