Made for your helm.
FULL HD TOUCHSCREEN
The sunlight-readable, anti-glare display includes an auto-dimming feature for low light or nighttime use. An in-plane switching LCD display provides consistent, accurate colours from all angles.
SIMPLE, ATTRACTIVE MOUNTING OPTIONS
Install multiple displays with the low flush-mount profile, or flat mount them edge-to-edge for a sleek glass helm look. The maximum glass design puts a powerful, networked helm at your fingertips.
Connect to everything on your boat.
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 autopilots, digital switching, weather, your 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 notifications2 , software updates, Helm, Garmin Quickdraw™ Community data and more.
It’s easy to connect to peripheral devices with built-in Wi-Fi connectivity, ANT technology, four wired Ethernet ports, NMEA 2000, HDMI and USB ports with complete network compatibility.
This feature brings together all the operations and capabilities of third-party devices, such as EmpirBus™ digital switching, on one screen.
SMARTMODE STATION CONTROLS
Get quick, one-touch access to the information you need to ease high-stress situations such as docking. You can incorporate networked sonar, radar, cameras, media and more.
CONNECT WITH RADAR
You can add your choice of compatible Garmin marine radar, including our powerful xHD2 open-array radars, GMR Fantom™ open-array radars with MotionScope™ technology or xHD dome radars.
Garmin supports select Axis cameras and select FLIR cameras for surveillance and situational awareness on your vessel. And with our Surround View Camera System, get live bird’s-eye view video plus 360-degree helm visibility.
Sail and navigate with ease.
GARMIN SAILASSIST™ SAILING FEATURES
View laylines, race start line guidance, enhanced wind rose, heading and course-over-ground lines, true wind data fields and tide/current/time slider, wind angle, set and drift, wind speed and more.
Experience unparalleled coverage and detail with optional BlueChart® g3 coastal charts featuring integrated Garmin and Navionics® content and Auto Guidance2 technology.
This free, easy-to-use software feature instantly creates your own personalized HD fishing maps with 1’ contours. There’s no special surveying expertise required. You just fish while it creates maps (requires transducer, sold separately).
MULTIPLE DEPTH RANGE SHADING
Designate up to 10 different depth ranges — each with its own colour. This makes it easier to view target depths at a glance.
FAST, RESPONSIVE 10-HZ GPS
Your position and heading are refreshed 10 times per second to make your movement on the screen more fluid. Plus, GPS 24xd provides dual frequency precise location accuracy3 to within 1 meter.
