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.

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.
