Using the GPS Unit’s Navigational Tools
  • Manually Create a New Waypoint:
    • Change the screen to the Map Page.
    • Use the ROCKER button to move the pointer to the desired location on the map.
    • Press the ENTER/MARK button to create the new waypoint.
    • Use the ROCKER button to edit the name or additional information about the new waypoint.
    • Use the ROCKER button to select the ‘OK’ button and press ENTER to save the waypoint.
  • Navigating to a Prerecorded Waypoint:
    • Press the GOTO button.
    • Use the ROCKER button to scroll through the list to either the named location you created or ‘Waypoint’ and press the ENTER button.
    • Use the ROCKER button to scroll through the list to the desired waypoint and press the ENTER button to select the waypoint.
