Perfectly Designed for Power and Sail Vessels

A glass-bonded finish lens on the GMI 20 prevents fogging and increases contrast. Daylight readability is enhanced with a high contrast color scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control. Screens can be set to auto-scroll, cycling between pages automatically without your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customized for powerboat, sailboat, fishing, engine/fuel, plus several other user-specified profiles. Power is supplied by the NMEA 2000® network.

In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the new GPSMAP® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.
