routes and even create a Go To directly to the selected
waypoint.
You can create waypoints using three methods. Press
the ENTER/MARK key while at a location, create a
waypoint on the Map page, or enter coordinates for a
waypoint manually.
Marking Your Current Location

current location creating a new waypoint. You must
have a valid position (2D or 3D) x to mark your
current location.
To mark your current location:
1. Press and hold the ENTER/M�RK key until the
Mark Waypoint page appears. A default three-
digit name and symbol are assigned to the new
waypoint.
