Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin GPSMAP 923 is a 9-inch chartplotter built around a high-resolution WXGA IPS touchscreen with 50% more pixels than previous-generation 9-inch GPSMAP units. This is the non-sonar (chart-only) model, designed for navigation and as the hub of a connected Garmin marine system.
A preloaded worldwide basemap gets you started, while support for premium Garmin Navionics+ and Garmin Navionics Vision+ charts adds detailed coastal cartography, Auto Guidance and high-resolution relief shading. Built-in Wi-Fi pairs the unit with the ActiveCaptain app for chart updates, smart notifications and Garmin Helm remote viewing.
With Garmin Marine Network, NMEA 2000 and NMEA 0183 connectivity, the GPSMAP 923 shares data with radar, sonar modules, autopilots, engines and instruments across the vessel. The rugged IPX7-rated housing suits both bail-mount and flush-mount installation at the helm.
