Fully customisable user profiles display wind, depth and speed data. Plus, the GNX 20 includes an auto-scroll feature that rotates through data screens for hands-free operation.

Easy-to-read Display
Unique high-contrast hybrid display features large, easy-to-read digits scalable up to 36 mm tall. Offers 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.
Customisable Colour Background
Choose from 7 different backlight colours, or even create a customised colour, to achieve the screen that provides optimum readability for you.
Customisable User Profiles
Fully customisable 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 customise 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. The GNX 21 uses only 25 mA with 350 mW daytime usage, requiring no backlight and just 400 mW with a mid-level backlight setting at night.
NMEA® 2000
Monitor more than 50 marine and boat parameters, including GPS speed, water depth and temperature, wind direction, and wind speed from the NMEA 2000 bus. You can also add a NMEA 0183 device using the optional 7-pin bare-wire power/data cable.
