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.

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.

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.
