GNX™ 20 Marine Instrument with Standard Display - 4"

Marine Instrucment with Standard 4" LCD

  • Large, easy-to-read black digits and graphs on a white or color background provides high contrast and high visibility; choose from 7 customizable backlight colors
  • Glass-bonded display with anti-glare lens avoids fogging
  • Fully customizable user profiles for sail or power boating to display most important marine and vessel data
  • Low power consumption (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight)
  • 5 display configurations plus gauge and graph mode to display depth, speed, wind and 50+ marine and boat parameters

The easy-to-read GNX 20 marine instrument display with black digits on a white or color background clearly shows depth, speed, wind and 50-plus marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent daytime and nighttime readability with high-contrast digits scalable up to 36 mm.

The GNX 20 is the first glass-bonded marine instrument with a combination of directly driven LCD segments and a dot-matrix field to display graphical information. Its low power consumption - (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight) - is perfect for use on sailboats, and provides a valuable instrument for cruising and fishing. Fully customizable 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. It can be installed with the included low profile flush mount or an optional flat mount for the ultimate glass helm solution and custom look for your boat.

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.

Customizable Color Background

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. The GNX 20 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.

FAQ

Return Policy

We don't want to see you stuck with a part that is not right for your application, or that you no longer need.  We issue refunds every day to make sure our customers have a positive purchase experience.  All these are issued as refunds, we do not maintain store credits. Returns must be initiated within 30 days of receiving the order.

However, for various policy, safety, and regulatory reasons, a small number of items are non-returnable for credit.  These are normally noted on the product page and visible at the time of purchase.  See our Returns Policy for full details on product returnability.

For orders where the item has been received is incorrect, defective or has been damaged in transit, we will pay return shipping and either replace the item or refund the amount paid, at the customer's discretion.

If the reason for the return is different, the customer is responsible for inbound and outbound shipping costs.  Shipping costs paid on the original order are non-refundable.  For orders shipped free on our $99 Free Shipping offer, an amount may be deducted from your refund to cover outbound shipping costs if returned.

Special Orders are normally non-cancellable and non-returnable because a lot of additional work must be performed to obtain a special order part that is not ordered very often.  If we are able to facilitate a special order return, you may have up to a 30% restocking fee deducted from your refund to cover manufacturer restocking fees and other associated costs.

Refunds can only be returned to the same method of payment that was originally used to pay for the order.
