Overview

The Garmin 010-02687-01 is a 9" touchscreen chartplotter and sonar combo that comes bundled with a GT56 transom-mount transducer for traditional CHIRP plus ClearVü and SideVü scanning.

It starts with a worldwide basemap for general reference, and the microSD card slot (32 GB max) lets you add detailed chart coverage when you need it, including Garmin Navionics+ and Garmin Navionics Vision+ cartography, plus BlueChart g3 and LakeVü g3 options.

The 9" WSVGA display runs at 1024 x 600 pixels and uses touch with keyed-assist controls, which is handy when hands are wet or the boat is moving. Power input is 9 to 18 Vdc, and the unit carries an IPX7 water rating.

Key features

• 9" WSVGA touchscreen with keyed-assist controls (1024 x 600 resolution)
• Worldwide basemap for general navigation reference
• Accepts one microSD card up to 32 GB for optional charts and map updates
• GT56 transom-mount transducer included for Garmin traditional CHIRP, ClearVü and SideVü sonar views
• Built-in 500 W sonar output with CHIRP support (frequency ranges depend on the transducer)
• Built-in Wi-Fi (2.4 GHz) for ActiveCaptain features and wireless sharing with compatible ECHOMAP UHD2 units
• NMEA 2000 port plus one Garmin Marine Network port for compatible accessories and networking
• Runs on 9 to 18 Vdc power with a 3 A fast-acting fuse (included); max power draw 20.7 W

Charting and navigation

On the water, the screen is large enough to split charts and sonar without feeling cramped. The built-in receiver supports multi-band, multi-constellation positioning and updates at up to 10 Hz, which helps when you are weaving through channels, following contour lines, or marking structure on a drift.

For your own data, it stores up to 5,000 waypoints, 100 routes, and 50,000 track points, so it can handle a season of marks and tracks without constant housekeeping.

Sonar and transducer

The included GT56 transom-mount transducer covers traditional sonar plus ClearVü and SideVü scanning, so you can look under the boat and out to both sides without swapping hardware. The chartplotter supports CHIRP sonar and lists sonar depth up to 701 m (2,300 ft.) at 77 kHz, with real-world performance depending on transducer selection, installation, bottom type, and water conditions.

For best readings, mount the transducer where it stays in clean water at speed and is not in the path of prop wash. When routing the cable, keep it away from high-current wiring and ignition components to reduce interference.

Networking and system integration

Wi-Fi lets you pair with the ActiveCaptain app for software updates and data management, and it also enables wireless sharing of sonar, waypoints, and routes with another compatible ECHOMAP UHD2 on board. Typical phone-to-plotter range is up to about 32 m (105 ft.) in open air.

For a wired backbone, the unit includes a NMEA 2000 port to bring in common boat data like heading, depth, wind, engine information, and compatible VHF DSC functions. There is also a Garmin Marine Network port for compatible Panoptix, LiveScope, GCV, and select ECHOMAP devices, but it is not intended for some Garmin Marine Network products such as radar.

Installation and setup

You can mount it on a bail bracket at the helm or flush-mount it into a dash for a cleaner look. The 9" model measures 264 x 166 x 80 mm, and the installation guide calls for 118 mm of clearance behind the chartplotter for cabling and airflow.

Because the power range is 9 to 18 Vdc, it fits standard 12 V systems. On 24 V boats, plan on a step-down converter so the supply stays within range. Cover unused ports with the supplied weather caps to help keep the contacts from corroding in a damp console.

Who this is a good fit for

This setup makes sense for anglers who want SideVü and ClearVü detail on a single 9" screen, and for cruisers who want a chartplotter that can tie into NMEA 2000 instruments without turning the helm into a full electronics refit. It is also a straightforward upgrade when you want to share sonar and navigation data between stations using compatible ECHOMAP UHD2 units.
