To help you avoid weather and traffic on the water, the compact 4 kW GMR™ 18 HD+ dome radar is available as a bundled option with your GPSMAP chartplotter/sonar package.
Core Features Include:
Ultra High-definition Scanning Sonar
Get built-in Ultra High-Definition SideVü and ClearVü scanning sonars with vivid, high-contrast colour palettes to help distinguish fish from structure. GPSMAP® 923xsv also supports 1 kW CHIRP traditional sonar capabilities.
Panoptix Sonar Support
Pair with Panoptix or Panoptix LiveScope™ easy-to-interpret live sonar (transducer sold separately) to see all around your boat in real time.
Faster, Sharper, Smarter
With its added processing power and new slimline design featuring edge-to-edge glass and a smaller unit footprint, it’s easy to retrofit this 9-inch plotter in a wider range of dash configurations.
Improved Display Optics
New higher-resolution 9-inch displays offer improved sunlight readability with 50% more pixels than previous-generation 9-inch GPSMAP devices.
Optional Bluechart G3 Vision Charts
These optional charts offer the best of Garmin and Navionics® data, Auto Guidance3 technology and other premium navigation features.
GARMIN Marine Network
If you have multiple compatible Garmin devices on your boat, you can share information — such as maps, user data, radar and IP camera video — among them.
NMEA 2000® and NMEA 0183 Networks
Connect to compatible autopilots, digital switching, weather, Fusion-Link™ audio system, media, VHF, AIS and more from one screen.
Built-in Wi-Fi® connectivity pairs with the free all-in-one mobile app for access to the OneChart™ feature, smart notifications, software updates, Garmin Helm™ digital switching, Garmin Quickdraw™ Community data and more.
Integrated Ant Technology
Connect with some of your favourite devices, such as quatix® marine watches, gWind™ Wireless 2 transducers transducers, GNX™ Wind marine instruments and wireless remote controls.
Now you can connect your chartplotter to different kinds of engines, including select Yamaha engines.
This exclusive feature brings together all the operations and capabilities of select third-party devices, such as EmpirBus™ digital switching, on one screen.
