Overview

The Garmin 010-12931-00 is a 12 V vehicle power cable kit for powering compatible echo, echoMAP, and STRIKER chartplotters and fishfinders. It combines a 4-pin power cable with a 12 V vehicle power adapter, so the display can be powered from a plug-in 12 V source instead of a permanent hardwire run.

This setup is handy for portable fishfinder kits, ice-fishing bundles, or any boat where you use a dash-mounted 12 V outlet at the helm. It is also useful when you bring the unit off the boat between trips and want the same plug-in power option in a vehicle or on the trailer.

Compatibility comes down to the connector at the display. Confirm your Garmin unit uses the 4-pin power port before ordering, since different series use different plug styles.

Key features

• 12 V adapter kit for powering compatible echo, echoMAP, and STRIKER chartplotters and fishfinders
• Includes a 4-pin power cable and a 12 V vehicle power adapter
• 4-pin connector matches Garmin units that use the 4-pin power port
• Well suited to plug-in power setups on board where a 12 V outlet is already available
• Makes it easy to disconnect and stow the display when trailering or storing gear

What’s included

• 4-pin power cable
• 12 V vehicle power adapter

Installation and setup

Connect the 4-pin plug to the back of the display, then route the cable so it will not be pinched by a bracket or chafe on sharp edges. Keep the adapter end in a protected location and leave a small drip loop in the cable run so incidental water does not track straight into the outlet area.

Compatibility and fit

This cable is intended for Garmin echo, echoMAP, and STRIKER models that accept the 4-pin power connection. If your unit uses a different power connector, this kit will not mate to the display, so checking the port style on the back of the unit is the quickest fit check.

Use cases on board

A good match for anglers running a portable fishfinder setup, boaters who want quick plug-in power at a 12 V outlet, and anyone who powers up electronics while the boat is on the trailer or at the dock without rewiring the boat.
