8 GPSMAP 188/188C Sounder Owner’s Manual
BASIC OPERATION > CREATING AND USING WAYPOINTS
Creating and Using Waypoints
The Garmin GPSMAP 188/188C Sounder stores up to 3,000
alphanumeric waypoints with a user-defined symbol, comments,
and depth available for each waypoint. Waypoints can be created
using two basic methods:
ENTER/MARK Key—marks your present location, and provides
options to select a map location or map item from the map display.
Also, you can enter a new waypoint’s location coordinates
manually.
Graphically—defines a new waypoint location from the map
display using the ROCKER.
ENTER/MARK Key
The Garmin GPSMAP 188/188C Sounder’s ENTER/MARK key
quickly captures your present location to create a new waypoint.
The unit must have a valid position (2D or 3D) fix to mark your
present position. You can also use this option to manually enter
waypoint coordinates.
To mark your present position:
1. Press and hold ENTER/MARK until the New Waypoint
window appears. A default three-digit name and symbol is
created for the new waypoint.
2. To accept the waypoint with the default name and symbol,
highlight OK, and press ENTER.
3. To enter a different name, highlight the name field, and
press ENTER. Use the ROCKER to enter the new letter/
numbers, and press ENTER when finished. You can use up
to 10 characters for the name.
4. To select a different symbol, highlight the symbol field to the
left of the name, and press ENTER. Use the ROCKER to
highlight the new symbol, and press ENTER.
