Full System Integration

GPSMAP 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 MFD 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 MFD 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.


Garmin Marine Network and NMEA 2000® Network Support

Full-network compatibility allows you to add more to your boat. GPSMAP 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 1 monitor or across multiple monitors in multi-display systems.


Add Array or Dome Radar

You can add your choice of Garmin marine radar, including our 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

GPSMAP MFD 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.


Heading, Position Refreshed 10 Times per Second

Fast, responsive built-in 10 Hz 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.


Create Your Own HD Maps

Quickdraw Contours is a free, easy-to-use software feature that is already installed on your GPSMAP MFD. It instantly creates your very own personalized HD fishing maps with 1-foot contours. Tailor them to fit your needs. They are your maps. You own them. Keep the data to yourself or share it with Garmin or your friends. There’s no special surveying expertise required. You just fish while it creates maps. You don’t have to wait around or send your files away like other mapping software requires — your results appear instantly. Use with any Garmin Panoptix, any HD-ID™, any CHIRP-enabled, Garmin DownVü™ transducer or NMEA 2000-compatible depth transducer. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you!


Upgrade to Our 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 BlueChart g2 HD or BlueChart® g2 Vision® HD, which add Garmin-patented 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

It’s easy to connect to peripheral devices with built-in Wi-Fi® connectivity, ANT® technology, 4 wired Ethernet ports, NMEA 2000, HDMI and USB ports with complete network compatibility. It’s easier than ever to enjoy the full range of features provided by Garmin Helm and BlueChart® Mobile apps.


View, Control Your Device from a Smartphone or Tablet

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.


Multiple Depth Range Shading

Designate up to 10 different depth ranges each with its own color. Makes it easier to view target depths at a glance.


Commission Autopilot from Chartplotter

To make commissioning easier and more convenient, you can handle the entire autopilot commissioning process from your chartplotter screen.
