The device integrates via NMEA 2000 and Garmin BlueNet and can receive data on vessel, wind, engine, fuel, temperature and depth. It supports wireless connectivity to gWind sensors, marine remote controls and quatix smartwatches. Software can be updated via the ActiveCaptain app, and an adapter plate makes it possible to replace the GMI 20 in existing cut-outs. The GMI 40 can be purchased on its own or in packages with gWind transducers for wind measurement or DST820/GDT 43/GST 43 for depth, speed and temperature data. Instrument layouts can be customised as required. NOK 8,200
