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 colors 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.

Customize 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 customizable layouts, data and gauges allow you to place the information you need to see right where you want it.

With BlueChart Mobile 2.0, a free app downloaded from the App Store™, you can get reliable weather information while you plan marine routes on your iPad or iPhone then wirelessly transfer them to your boat’s compatible networked Garmin chartplotter. Continue to acquire current weather information from your cellular-based Apple® device, and stream that data onto your chartplotter screen. Even if you don’t have a Garmin chartplotter, you can still take advantage of the tremendous features of BlueChart Mobile on your compatible Apple device.
Multiple Depth Range Shading

Axis Camera Support
Garmin offers support for select Axis cameras, which can be used for surveillance and situational awareness on vessels of any size. Our integration allows you to view video on every screen on your boat and, if you wish, view multiple streams on the same screen. You can control your camera's pinch-to-zoom and pan/tilt settings with gestures directly on the plotter screen. Use an Axis encoder to convert analog camera, such as Garmin GC 10, to video over IP.
