Description

The Garmin GMI 20 brings vessel data to life on a bright 4-inch bonded colour display. Extra-large digits keep readings legible from across the cockpit, while the 170-degree viewing angle and anti-glare glass lens preserve clarity in direct sunlight. Drawing both power and data from a NMEA 2000 network, the GMI 20 presents depth, speed, wind, engine information and over 100 marine and vessel-specific parameters, with customisable data pages to suit how you sail or cruise. The glass-bonded construction prevents condensation forming inside the unit, and the fully-gasketed polycarbonate case carries an IPX7 waterproof rating. It can also display NMEA 0183 data from a connected source, and Nexus sensor data through a GND 10. Flush mounting is straightforward using the supplied template and hardware.
