Serious sport fishermen, cruisers, sailors and sail racers demand serious equipment. The easy-to-use, easy-to-install GPSMAP chartplotter/sonar combo delivers MFD performance in a combo-size package. It features a full HD in IPS touchscreen display for wider viewing angles, superior clarity and sunlight readability, even with polarized sunglasses. Multiple displays can be flat mounted edge-to-edge to create a sleek glass helm look or can be mounted flush.


Complete Sonar Support


The GPSMAP chartplotter/sonar combo offers built-in support for our industry-leading sonar, including dual-channel 1 kW traditional CHIRP, CHIRP ClearVü and CHIRP SideVü scanning sonars plus built-in support for Ultra High-Definition scanning sonar (no black box required). It also supports the entire Panoptix™ all-seeing sonar line (transducers sold separately).

Build Your Marine System


NMEA 2000 networking and the Garmin Marine Network allow you to easily build your full marine electronics suite — from radar and autopilots to cameras, instruments and forward-looking sonar — controlled from your chartplotter and shared across multiple screens. In addition, our exclusive OneHelm™ system coordinates many third-party manufactured onboard marine products to bring full control of systems — such as digital switching, lighting, stabilization and more — conveniently to your chartplotter screen.


Full Connectivity


The GPSMAP chartplotter has a premium-performance processor that enables fast map drawing, superior networking, video distribution and more. Built-in Wi-Fi technology lets you pair with the free ActiveCaptain® app for access to OneChart™, smart notifications¹, Garmin Quickdraw™ community data and more. You can also control video streaming from our GC™ 100 wireless camera and VIRB® action cameras. In addition, built-in ANT wireless technology connects you directly to our quatix® marine watch, gWind™ Wireless 2 transducer and wireless remote controls.


SmartMode Station Controls


Networked sonar, radar, cameras, media and digital switching can be independent or incorporated into SmartMode station controls. With SmartMode, everything is designed to give you quick, one-touch access to the information you need to ease high-stress situations such as docking.

Special Sailing Features


The Garmin SailAssist™ feature provides data, displays and prerace guidance to help you gain a competitive edge. Other sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, true wind data fields and tide/current/time slider. Gauge displays provide 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 fields.
