Overview

The Garmin 010-11843-01 is a hardwire power and ground cable used with a compatible zumo motorcycle mount bracket (sold separately) to keep a zumo 350LM powered from a 12 V DC system while it is in the cradle. It is meant for a fixed install where you want continuous power for the navigator instead of relying on the internal battery.

Because this cable is part of the mount-and-cradle power setup, it is not a USB charging lead and it does not plug directly into a chartplotter or marine network. It is a straightforward way to bring 12 V power to the zumo mount so the device powers through the cradle connection.

Compatibility commonly includes zumo 340LM, 345LM, 346LMT-S, 350LM, 390LM, 395LM, and 396 LMT-S. If you are using it on a boat, plan on installing it in a protected location and routing the wiring where it will not see spray, washdowns, or constant UV exposure.

Key features

• Hardwire power and ground connection for 12 V DC vehicle-style electrical systems
• Works in conjunction with the zumo motorcycle mount bracket (sold separately) so power is delivered through the cradle
• Supports multiple zumo 3xx models, including zumo 350LM and other commonly paired units in the series
• Useful for clean wiring runs behind a dash, console, or fairing where you want the cable secured and out of the way

Installation and setup

Connect the cable to a properly protected 12 V DC circuit and a solid ground, then route it to the mount bracket location with enough slack for steering movement and vibration. On boats, use cable clamps and chafe protection anywhere the run passes through bulkheads, under a console, or near sharp edges, and keep all connections above the lowest point where water can collect.

This accessory is part of a cradle-powered setup, so the mount bracket matters as much as the cable. Confirm the bracket you have is the correct one for your specific zumo model and that it is positioned where the zumo can be inserted and removed without putting strain on the wiring.

Compatibility and fit

This cable is intended to feed power to the compatible zumo motorcycle cradle system and should be matched to the correct mount bracket for your device family. It is not interchangeable with Garmin chartplotter power leads, NMEA wiring, or marine radar and GPS extension cables.

Use on board

This is a practical add-on for boaters who keep a zumo unit as a portable navigator and want it powered at the helm from the boat’s 12 V supply. It makes the most sense on small craft, tenders, and runabouts where the install stays sheltered and the unit can be removed when the boat is unattended or conditions turn wet.
