Garmin GMI™ 20 Marine Instrument
The Garmin GMI™ 20 is a marine instrument designed to display depth, speed, wind, and over 100 marine and vessel parameters across a 4.0-inch display. This unit is installed on coastal cruisers to provide essential navigational data for both power and sail vessels.
Compatibility & Applications
- Wires to NMEA 2000 networks for integration with other marine electronics.
- Pairs with a variety of sensors for depth, speed, and wind measurements.
- Mounts easily on dashboards of vessels ranging from 20 to 40 ft.
- Replaces older Garmin GMI 10 models without requiring additional modifications.
- Fits in standard 3.5-inch mounting holes commonly found in marine installations.
- Integrates with multifunction displays for enhanced data visualization.
The unit provides real-time data for navigation and performance monitoring, enhancing vessel operation. It serves as an effective drop-in replacement for outdated instruments, improving functionality without extensive rewiring. For example, during a retrofit on a 30 ft sailboat, the GMI™ 20 can replace older gauges, allowing for streamlined data collection and improved accuracy compared to generic models.
