Integration is simplified by NMEA 2000 compatibility, allowing the GMI 20 to communicate with existing Garmin sensors and devices. While the GMI 20 instrument does not directly receive NMEA 0183 data, it can display information from NMEA 0183 sources connected to a GNX 20 or GNX 21 device (sold separately) on the same NMEA 2000 network. It can also receive data from Nexus instruments via a GND 10 device (sold separately).

Durable Design and Technical Specifications

The GMI 20 display is built to withstand harsh marine environments. Its housing is fully sealed polycarbonate, and its lens is anti-glare glass. It meets IEC 60529 IPX7 waterproofing standards, ensuring accidental immersion up to 1 meter for 30 minutes. The device operates across an extended temperature range from -15°C to 70°C. Its compact dimensions (110 x 115 x 30 mm without solar cover) and lightweight (247 g without solar cover) facilitate installation. The unit consumes a maximum of 1.35 W, and its NMEA 2000 Load Equivalency Number (LEN) is 3 (150 mA at 9 Vdc), ensuring low power demand on the network. The pack includes a flush-mount template, and a flush-mount kit is available as an option for aesthetic integration. The compass-safe distance is 209 mm, a critical detail for dashboard installation planning.
