GPSMAP 8424 large-format multifunction display features convenient touchscreen control. Sunlight-readable, anti-glare display is exceptionally easy to view and also includes an auto-dimming feature for use in low light or at night. The 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. Preloaded worldwide basemap included for general reference.

Full System Integration
The MFD integrates various sonar technologies as well as autopilot, connectivity, apps, engine data, and multi-media. User data can be automatically synced for all networked networked 8400/8600 series chartplotters across multiple helms - everything you need is at your fingertips and on one 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, programmed into a remote key fob, or through an app on your tablet provided by CZone by Mastervolt.

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

Customize Layouts With SmartMode Control
To make boating easier, the unit 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, such as fishing, docking, night cruising, etc. One-touch access allows you to switch all monitors in sync from one 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.

Garmin Marine Network And NMEA 2000 Network Support
Full-network compatibility allows you to add more to your boat. MFD 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.

View Multiple Sonar Sources Simultaneously
GSD 26 CHIRP professional sonar, GSD 24 advanced sonar, and GCV 10 or GSD 25 DownVü and SideVü scanning sonar, even Garmin Panoptix all-seeing sonar can exist on the same system. You can view various sonars together on one monitor or across multiple monitors in multi-display systems.

Add Array or Dome Radar
You can add your choice of Garmin marine radar, including the powerful xHD2 open-array radars, GMR Fantom open-array radars with MotionScope technology, or xHD dome radars that pair ease of use with advanced open-array features.

Network Sharing
This 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 one chartplotter can be automatically synced with other chartplotters in a network.

Heading/Position Refreshed 10 Times Per Second
Fast, responsive built-in 10Hz GPS refreshes your position and heading 10 times each second to make your movement on the screen more fluid. Now it's quick and easy to drop up to 5,000 accurate waypoints and find your way back to them.

SailAssist Features
Supported sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, true wind data fields, and tide/current/time slider. Racing features include pre-race guidance, synchronized race timer, virtual starting line, time to burn, and layline data fields. Gauge displays are designed to provide important, need-to-know information at a glance, including true and apparent wind angle, set and drift, true or apparent wind speed, horizontal or vertical graphs, and a data bar with customizable data fields.

Upgrade to Garmin's Best Maps On The Water
Add a Garmin Card Reader that provides convenient remote mounting and a single access point for 2 SD card slots for accessory map purchases such as LakeVü HD Ultra with MaxDef Lakes, BlueChart g2 HD, or BlueChart g2 Vision HD, which add Garmin Auto Guidance 3.0 and other great features. You can add multiple card readers for additional access points. Waterproof magnetic door allows card reader to be mounted horizontally or vertically (sold separately).

FUSION-Link Entertainment System
Enjoy the ability to control all compatible FUSION-Link-enabled audio systems directly from your compatible chartplotter display.

Built-In Connectivity
Garmin Helm allows you to view and control your compatible chartplotter from a compatible smartphone or tablet while providing enhanced situational awareness for the mariner. Easily switch between portrait and landscape modes to accommodate mounting preferences. When using an iPhone or iPad, you can even record a movie of your chartplotter screen to share with friends and family.

Get Onboard With BlueChart Mobile
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.
