Discover the Versatility of the Garmin GMI 20 on Your Boat

Imagine glancing at a single, vibrant screen that pulls together every critical piece of data your vessel needs—depth readings for safe navigation, speed logs for performance tracking, wind angles for precise sailing maneuvers, and much more. The Garmin GMI 20 steps in as your reliable marine instrument hub, tailored for both powerboats and sailboats. Its 4-inch color display stands out with oversized digits visible from afar, even in choppy conditions, thanks to a wide 170-degree viewing angle.

Boaters rave about how this unit simplifies helm setups. No more squinting at tiny analog gauges or juggling multiple screens. Connect it seamlessly to your NMEA 2000 network, and it starts displaying over 100 parameters from compatible sensors and transducers. Customize screens for your style—power cruising, competitive racing, or casual fishing—and let auto-scroll handle the rest, freeing you to focus on the water.

Standout Features That Elevate Your Boating Experience

Crystal-Clear Visibility: Glass-bonded lens fights fog and glare, delivering sharp contrast in blinding sun or pitch-black nights.
Adaptive Night Modes: Switch between full color, red-on-black, or green-on-black schemes with adjustable dimming to preserve your night vision during long passages.
Sailor-Friendly Tools: Built-in race countdown timer with audible alerts keeps you on pace, while customizable profiles match powerboat speed runs or sailboat tack optimizations.
Flexible Mounting: Comes with snap-on trim covers in black or silver to blend perfectly with Garmin chartplotters like the GPSMAP series.
Network Powered: Draws clean power directly from NMEA 2000—no extra wiring hassles.

Whether you're dodging reefs in shallow waters or trimming sails for a regatta, the GMI 20 proves indispensable. Its polycarbonate build holds up to saltwater splashes (IPX7 waterproof) and extreme temps, making it a go-to for offshore adventurers.

Effortless Setup and Customization Tips

Installing the GMI 20 feels straightforward, even for weekend warriors. Flush-mount it using the included gasket and hardware, or surface-mount with the sun cover for added protection. Drop it onto your NMEA 2000 backbone via the T-connector and drop cable—most setups take under an hour.

Pro tip: Start with default profiles like "Sail Racing" for wind data overlays or "Engine/Fuel" for motor yachts. Tweak data fields to show true wind speed, water temp, or fuel flow exactly where you need them. For multi-unit installs, sync them to auto-cycle pages, creating a unified dashboard across your cockpit.

Maintenance is minimal—just rinse with fresh water after salty outings and store the protective cover when not in use. Compass-safe at 209 mm away, it won't throw off your steering.

GMI 20 Marine Instrument Display

Perfectly Designed for Power & Sail Vessels

The GMI 20 digital marine instrument display is perfectly designed for both power and sail vessels. Designed to clearly show depth, speed, wind and 100+ marine and vessel parameters, its large, bright 4" color display with extra large digits is easy to read at a distance and 170 degree viewing angle.

A glass-bonded finish lens prevents fogging and increases contrast. Daylight readability is enhanced with a high contrast color scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control. Screens can be set to auto-scroll, cycling between pages automatically without your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customized for powerboat, sailboat, fishing, engine/fuel, plus several other user-specified profiles. Power is supplied by the NMEA 2000 network.

In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the GPSMAP 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.
