	Designed for serious sailors who demand quality, precision and total 
integration, this high-precision glass-bonded 7-inch large format instrument 
creates a beautiful “glass mast” display with superior readability day and 
night. It allows seamless sharing of sailing data between Garmin devices and is

use.
Superior Readability
	Enjoy superior readability in all conditions, day and night¹. Options for 
white or color 2-inch (51 mm) digits — the largest in class — allow you to 
adjust for most preferred visibility setting for any lighting condition. The GNX 
120 provides a flush mount glass mast look, and its glass-bonded high-contrast 
monochrome LCD display avoids fogging. Low power consumption of 0.36 W daylight 
with no backlight and 0.4 W nighttime with mid-level backlight preserves your 
batteries.
Customize Your Profile
	Fully customizable user profiles allow you to configure the screen layout to 
your preferred setting. Five display configurations are available: single, dual 
and triple function, plus Gauge and Graph modes, to display data for more than 
50 important marine parameters for wind, sea and vessel conditions. Display data 
from Expedition software on the instrument using a Actisence NGT-1 N2K USB or 
GND 10 (not required). Adrena and SmartSkipper information can also be displayed 
using the GND 10.
	¹Color backlight is not visible in daylight.
Easy-to-read Display
	Unique high-contrast hybrid display features the largest digits in class. 
Easy-to-read digits are 2-inches (51 mm) tall. Adjust to your preference of 
white or color digits for excellent clarity in direct sunlight, at dusk, or at 
night. The dot-matrix section can show additional details and/or graphical 
information.
Glass-bonded Display
	Glass-bonded display helps prevent fogging, and the anti-glare lens finish 
increases visibility.
Tailor Display for Optimum Viewing
	Choose from 7 different backlight colors, or even create a customized color, 
to achieve the screen that provides optimum readability for you.
Customizable User Profiles
	Fully customizable user profiles allow you to choose from 5 available display 
configurations for sailboat or powerboat user-profiles: single, dual and triple 
function, plus Gauge and Graph mode to display wind, depth and speed data or 
customize the pages to display the marine and boat data that is most important 
to you.
Auto-scroll
	Set your display to automatically cycle between pages at a speed you set for 
convenient, hands-free operation.
Low Power Consumption
	Perfect for sailors who want to sail for long intervals without having to run 
a motor or generator to charge batteries. Uses only 0.36 W daytime usage 
requiring no backlight and just 0.4 W with a mid-level backlight setting at 
night.

depth and temperature, wind direction and wind speed from the NMEA 2000 bus.
