Introducing the Garmin GNX120 7-inch Large Format Marine Instrument, a high-precision glass-bonded display that acts like a “glass mast” at the helm. Built for serious sailors who demand quality, precision, and total integration, this instrument brings day-and-night readability, a wealth of data, and seamless Garmin ecosystem connectivity to your cockpit.

Crystal-clear visibility in any condition – a 7-inch display with a high-contrast monochrome LCD and a flush-mount glass mast look. The glass-bonded design prevents fogging, delivering crisp readouts when it matters most. Choose from bold 2-inch (51 mm) digits—the largest in class—to ensure quick reference in any lighting scenario. Designed for minimal power use, it draws only 0.36 W in daylight (no backlight) and 0.4 W at night (mid-level backlight), preserving your battery on longer trips.

Key benefits

• Displays 50+ marine parameters for wind, sea state, and vessel conditions, giving you comprehensive insight at a glance.
• Premium readability with day/night visibility and the largest digits in its class.

Seamless Garmin ecosystem and data sharing

Designed for total integration, the GNX120 shares sailing data effortlessly between Garmin devices. Control and data exchange are streamlined from a compatible GNX keypad, letting you manage information across your instruments with ease. For advanced data displays, Expedition software data can be shown on the instrument using an Actisence NGT-1 N2K USB or GND 10 (not required). Adrena and SmartSkipper information can also be displayed with the GND 10, expanding your navigation and race-management capabilities.
