Essential Data at Your Fingertips
Bring the information you need into clear view with the Garmin GMI 40 Multipurpose Marine Instrument. Its 4.3-inch, high-resolution color touchscreen displays live wind, speed, depth, heading, engine and fuel data from compatible onboard devices. Edge-to-edge glass and a streamlined design give it a clean look alongside Garmin GPSMAP chartplotters.
Set up the display around the way you use your boat. Customizable gauge sets and page layouts let you keep essential readings easy to see, whether you’re watching wind conditions under sail, checking depth along the coast or monitoring engine and fuel information on a cruise.
The GMI 40 connects to compatible equipment through NMEA 2000 and Garmin BlueNet. It also supports wireless connectivity with compatible gWind sensors, marine remote controls and Garmin quatix smartwatches. With data from across your onboard system in one place, you can keep your chartplotter focused on navigation while the GMI 40 shows the instrument readings you you rely on.
Built for the marine environment, the GMI 40 features an anti-glare glass display and an IPX7 water-resistance rating. You can update its software through the ActiveCaptain app on a compatible smartphone. This model includes the GMI 40 instrument; the data it displays depends on the compatible sensors and equipment connected to your boat.
