Waypoint Lists
The GPSMAP 178C’s Main Menu Page features two waypoint submenu tabs, ‘User’ and ‘Proxim-
ity’, that let you manage a large number of waypoints quickly and effi ciently. The submenu tabs also
provide a continuously updated proximity waypoint alarm function that can be used to defi ne an alarm
circle around submerged hazards, shallow waters, etc.
To access the waypoint submenus of the Main Menu:
1. Press MENU twice, highlight the ‘Points’ tab using the ARROW KEYPAD, then highlight the
desired submenu tab.
User Waypoint List
The ‘User’ submenu of the Points tab displays a master list of all waypoints currently stored in
memory. From the User list, you may review, edit, rename or delete individual waypoints, or delete all
user waypoints. The total number of stored and available waypoints is displayed at the bottom of the
User page, with the stored waypoints arranged in numerical/alphabetical order.
To scroll through and review the waypoint list:
1. With the ARROW KEYPAD, highlight the ‘Points’ tab on the main menu, then highlight ‘User’.
2. Use the ARROW KEYPAD to scroll through the list in the desired direction.
3. Press ENTER to review the highlighted waypoint on the ‘Waypoint Edit’ page (see page 48 for
detailed information on reviewing and editing waypoints).
4. With ‘Next’ highlighted, press ENTER to return to the list. The fi eld highlight automatically moves
to the next waypoint in the list.
The following options are available by pressing MENU while highlighting the Points tab, the User
submenu or one of the User waypoint names:
• Create Waypoint— allows you to create a waypoint. (See page 44)
