Deleting Waypoints
Main Menu Page
As you’ve seen, the primary pages provide map, sonar, and navigation information. The tour’s last page
is the Main Menu Page, which allows access to the GPSMAP 178/178C Sounder’s waypoint, route, and
planning functions, as well as various operational and navigation setup features, and celestial and tide data.
The Main Menu is available from any page, and is accessed through the MENU key.
To access the main menu page:
1. Press the MENU key twice (or hold down the MENU key for two seconds.).
The Main Menu Page lists 16 vertical ‘tabs’ that are divided into categories by function. You can
view a particular menu by simply highlighting the desired tab, which shows any secondary (horizontal)
submenu tabs and options for that tab.
To get a basic feel for how the Main Menu Page works, let’s delete the two waypoints you created
during the simulated tour. This ensures that you have a clean slate once you start navigating in your
home waters.
To delete the practice waypoints:
1. Use the ARROW KEYPAD to highlight the ‘Points’ menu tab. You see a list of stored waypoints
appear to the right of the Main Menu list.
2. Press RIGHT one time on the ARROW KEYPAD to highlight the ‘User’ submenu tab.
3. Press DOWN on the ARROW KEYPAD and highlight waypoint ‘001’ with the shipwreck symbol.
4. You may delete the waypoint by either pressing MENU, then highlighting ‘Delete Waypoint’; or by
pressing ENTER and then highlighting ‘Delete’ from the Waypoint Edit Page.
5. Press ENTER to delete the waypoint, then ENTER again to confirm. Repeat the above steps to delete
the ‘Dock’ waypoint also.
