Creating and Using Waypoints
The Garmin GPSMAP 178C stores up to 3000 alphanumeric waypoints with a user-defi ned icon,
comments, depth, or water temperature available for each waypoint. Waypoints can be created using
three basic methods:
• ENTER/MARK key– used primarily for marking your present position, the ENTER/MARK key
also provides options that allow you to select a map position or map item from the map display.
• Graphically– allows you to defi ne a new waypoint position from the map display using the
ARROW KEYPAD. (For creating underwater waypoints, see page 37)
• Text Entry– allows you to enter a new waypoint’s coordinates manually (from a chart, etc.).
Marking Your Present Position
The Garmin GPSMAP 178C’s ENTER/MARK key lets you quickly capture your present position
(or cursor or map item position) in order to create a new waypoint. You must have a valid position
(2D or 3D) fi x to mark your present position. This can be determined by looking at the GPS tab on the
Main Menu.
To mark your present position:
1. Press and hold the ENTER/MARK key until the ‘New Waypoint’ window appears, then release it.
You see a default three-digit name and symbol for the new waypoint.
2. To accept the waypoint with the default name and symbol, press ENTER to confi rm the highlighted
‘OK’ prompt.
3. To enter a different name, highlight the name fi eld and press ENTER, then use the ARROW
KEYPAD to enter the new letters/numbers and press ENTER when done. You may use up to 10
alphanumeric characters for the name.
4. To enter a different symbol, highlight the symbol fi eld to the left of the name and press ENTER,
then use the ARROW KEYPAD to highlight the new symbol and press ENTER.
5. To enter optional comments, depth, or water temp, highlight the appropriate fi eld and press
ENTER, then use the ARROW KEYPAD to enter a value and press ENTER.
Highlight ‘OK’ and press ENTER to
use the default name and symbol.
