Nautical instrument with standard 4″ LCD screen
- Large digits and graphics with good readability of black color on a white or colored background that offer high contrast and magnificent visibility; choose from 7 customizable backlight colors
- Screen with attached glass with anti-reflective lenses that prevents fogging
- Fully customizable user profiles for navigation with sailing or motor boats that allow you to view the most relevant nautical data and the boat.
- Low power consumption (25 mA) with a use of 350 mW (without backlight)/400 mW (medium level backlight)
- 5 screen settings and graph and indicator modes to display information related to more than 50 navigation parameters, in addition to depth, speed or wind data
The easy-to-read screen of the GNX 20 nautical instrument uses black digits on a white or colored background to display information related to more than 50 navigation parameters, in addition to depth, speed or wind data. The screen with adhered glass with anti-reflective coating provides excellent readability for both day and night, as well as high-contrast digits that can be enlarged up to 36 mm.
The GNX 20 device is the first nautical instrument with a screen with attached glass that presents a combination of LCD segments by direct drive and a matrix field of points that allows graphic information to be displayed. By consuming little energy (25 mA) with a use of 350 mW (without backlight)/400 mW (average level of backlight), this device is ideal for sailing boats, as well as a very useful instrument during navigation and fishing activities. Fully customizable user profiles show data related to wind, depth and speed. In addition, the GNX 20 device includes an automatic screen change function that allows you to switch between data screens without user intervention. It can be installed with the low-profile built-in mounting bracket or with the optional flush mounting bracket in order to enjoy the best glass rudder solution and customize your boat as you wish.

FAQs
Drill 2.8 mm (7/64 in.) pilot holes for securing the GNX 20 during installation.
Cover unused connectors with the attached weather caps to prevent corrosion.
Yes. Place the included gasket on the back and apply marine sealant around it to prevent leakage.
Always check what is on the opposite side of the surface to avoid damaging the vessel.
Always check the opposite side of the surface before drilling or cutting to avoid damaging the vessel.
Use a countersink bit to drill a clearance counterbore through only the top gel-coat layer; this avoids cracking the gel-coat.
Install the device at least 209 mm (8.25 in.) away from a magnetic compass.
No, connect it to the boat ignition switch or an in-line switch. Connecting it directly to the battery may drain the battery.
Yes, the mounting surface must be flat to avoid damaging the device when it is mounted.
The NMEA 2000 Load Equivalency Number (LEN) is 3 (150 mA at 9 Vdc).
It is powered through the NMEA 2000 network; only one NMEA 2000 power cable is required for the network.
Yes, it can receive NMEA 0183 data using a NMEA data cable (not included).
No, a NMEA 0183 data cable must be purchased separately if needed.
The case is fully-gasketed polycarbonate; the lens is glass with an anti-glare finish.
