GPSMAP 8424 large-format multifunction display features a 24-inch full HD screen with touch control. Sunlight-readable, anti-glare display is exceptionally easy to view and also includes auto-dimming feature for use in low light or at night. New maximum glass design enables you to experience a beautifully powerful, completely networked helm at your fingertips. In-plane switching (IPS) LCD display — an industry first for this class — provides consistent, accurate colours from all viewing angles. It also provides standard USB touch output for use as a touchscreen monitor for Windows and Mac operating systems. Install multiple displays with the industry’s lowest flush-mount profile or flat mount them edge-to-edge to create a sleek glass helm look. Quick, 1-touch access to the information you need makes boating easier.

Full System Integration

GPSMAP 8424 integrates various sonar technologies as well as autopilot, connectivity, apps, engine data and multi-media. User data can be automatically synced for all networked 8400/8600 series chartplotters across multiple helms — everything you need is at your fingertips, all on 1 screen. A full digital switching system uses CZone technology. You can power up your boat while away from the dock, switch on pumps and control lights — even underwater lights. Nearly all of your controls are available right at your fingertips either at the helm or programmed into a remote key fob or an app on your tablet provided by CZone by Mastervolt.

New High-performance Processor

Experience the fluidity of our fastest map drawing ever and enhanced video processing. Add up to 4 IP camera streams and simultaneous Garmin Helm support. In addition, all your added sensors, such as radar, sonar, multimedia and more, will benefit from the increased performance to provide a premium experience across your boat’s entire network. 

Customise Layouts with SmartMode Control

To make boating easier, GPSMAP 8424 includes presets for sonar, radar, cameras, media and digital switching, which can be independent or incorporated into SmartMode. With SmartMode control, you can quickly change all screens at a helm in sync to a preset mode, for example, fishing, docking, night cruising, etc. One-touch access allows you to switch all monitors in sync from 1 mode to another without manually switching each monitor separately. Fully customisable layouts, data and gauges allow you to place the information you need to see right where you want it.

Full-network compatibility allows you to add more to your boat. GPSMAP 8424 supports radar, autopilot, instruments, multiple screens, FUSION-Link entertainment system, sensors, remote sonar modules, digital switching, weather, thermal cameras, GRID remote device and more. It’s also FLIR camera compatible and provides SiriusXM support.

Network Sharing

GPSMAP 8424 allows you to share features with other compatible GPSMAP units such as radar, supplemental maps and user data, including waypoints, routes and tracks. You can also share images from Garmin VIRB action cameras, GC 10 marine cameras and FLIR cameras. User data entered into 1 chartplotter can be automatically synced with other chartplotters in a network.
