Overview

The Garmin 010-10747-03 is a 12-volt adapter cable that powers compatible Garmin nuvi GPS units from a cigarette-lighter style accessory socket. It is a practical way to keep a nuvi running at the helm when you are using an automotive-style GPS as a backup navigator on a boat with a 12V outlet.

The cable run is approximately 1.5 meters, which is usually enough to reach from a dash outlet to a windshield-style mount or a small bracket at the console. On supported nuvi models, this lead connects to the power cradle (mount) rather than plugging into the GPS itself, and it is power-only with no built-in traffic receiver function.

Key features

• Plugs into a standard 12V DC cigarette-lighter style accessory receptacle
• Approximately 1.5 m cable length for flexible routing at the dash or helm
• Designed to feed power through the mounting cradle on compatible nuvi mounts
• Power-only lead that does not add TMC traffic receiver capability

Compatibility and fit

This adapter cable is used with Garmin nuvi models that take vehicle power through a powered cradle. Confirm that your mount has the side power input used by the nuvi 600 series (600, 610, 650, 660, 670, 680, including “T” and “FM” variants) and the nuvi 700 series (700, 710, 750, 755, 760, 765, 770, 775, 780, 785, including “T” variants).

Installation and setup

Plug the accessory end into a 12V outlet, then connect the other end to the power input on the nuvi mounting cradle. Route the cable so it stays clear of steering gear, throttle linkages, and sharp edges, and leave enough slack for the mount to pivot without pulling on the connector.

For open helms, treat it like any cabin electronics lead: keep the plug and connection points out of spray, avoid standing water, and secure the cable so vibration does not work it loose.

What’s included

• Vehicle power cable

Use cases on board

This is a good match for boaters who run a portable nuvi at the helm for quick routing reference or as a secondary display while the primary chartplotter handles navigation. It also works well for moving the same GPS between a tow vehicle, an RV, and the boat when you rely on a 12V accessory outlet for power.
