GPSMAP 172/172C Getting Started Tour

The Garmin GPSMAP 172/172C is a powerful electronic navigation system that provides detailed 

map coverage and convenient control of many advanced features right from the screen display. This 
tour is designed to take you through the basic pages and functions of the system using the simulator 
mode. Once you’re familiar with the main pages and functions of the unit, refer to the reference section 
for instructions on performing specific tasks and functions. For GSD 20 sonar related operations, refer 
to “GSD 20 Sounder Module with Garmin Chartplotters” (190-00241-03).

The Getting Started Tour assumes that the receiver has been properly installed and initialized, and 

you have not changed any of the default unit settings. If you have changed any settings (position for-
mats, units of measure, etc.), the descriptions and pictures in the tour may not match your configura-
tion.

1.  Press and hold the POWER key until the power tone sounds, then release the POWER key. The 

Warning Page appears while the unit conducts a self-test.

2.   Once the self-test is complete, press the ENTER/MARK key, if you agree, to acknowledge the 

warning.

The GPS Information Page appears as the receiver begins acquiring satellites. From this or any 

other page, you may also adjust the screen backlighting.

The GPSMAP 172/172C’s adjustable screen backlighting is controlled with the POWER key. The 

backlight can cycle through minimum, user-defined, and maximum backlight levels by repeatedly 
pressing the POWER key.

1.  Press POWER and the Light/Contrast window appears. 
2.   Press POWER again and the user-defined level of backlighting activates. You may adjust this level 

by pressing UP or DOWN on the ARROW KEYPAD. If you press POWER one more time, the back-
lighting is at the minimum setting. Press LEFT (brighter) or RIGHT (darker) to adjust the contrast. 

3.   Press ENTER or QUIT when done.

A full-screen GPS Information pop-up page is displayed 
after you press the ENTER key to acknowledge the  
Warning Page. The pop-up page goes away after the unit 
gets a position fix or you press either ENTER or QUIT.
