Overview

The Garmin 010-12954-00 is a GLS 10 sonar module that links a LiveScope transducer to a compatible Garmin chartplotter over the Garmin Marine Network for live, real-time scanning sonar views. It runs on 10 to 32 Vdc (12V or 24V systems) and draws about 21 W in normal use (up to 58 W), with a compact black-box footprint of 245 x 149 x 65 mm (9.7 x 5.9 x 2.6 in.).

This module is the hub for LiveScope setups, taking the transducer signal and putting it on the network so it can be displayed and shared on connected Garmin chartplotters. It works with compatible LiveScope transducers including LVS32, LVS34, and LiveScope XR LVS62 (transducer sold separately).

It is a good match for boats that already have Garmin Marine Network on board and want to add LiveScope, replace a GLS 10 module, or run LiveScope views on more than one networked display.

Key features

• 10 to 32 Vdc input for 12V and 24V electrical systems.
• Power draw rated at 21 W typical and 58 W max for planning wiring and load.
• 7.5 A fast-acting fuse integrated on the power lead.
• Garmin Marine Network data output with 1 network port (small connector).
• Compatible with LiveScope transducers including LVS32, LVS34, and LiveScope XR LVS62 (transducer not included).
• 245 x 149 x 65 mm housing and 1.96 kg (4.33 lb) weight for mounting planning.
• Compass-safe distance listed at 178 mm (7 in.) to help avoid interference near compasses and sensors.
• Status LED supports quick checks for connected, waiting to connect, updating, and fault conditions.

What’s included

• GLS 10 sonar module
• Power cable with in-line fuse
• 2 m Garmin Marine Network cable (small connector)
• Garmin Marine Network adapter cable (small connector to large)
• Mounting hardware
• Documentation

Compatibility and fit

The GLS 10 connects to a compatible Garmin chartplotter through the Garmin Marine Network, so your display needs network support for LiveScope. If your boat already has a Garmin Marine Network backbone for radar or chart sharing, the module can be added as another network device so LiveScope views are available on connected stations.

Plan the mounting location with the compass-safe distance in mind, and leave room at the connectors for a clean cable bend radius and service access.

Installation and setup

Mount the module in a location where it will not be submerged, with the status LEDs visible and the cables able to reach without strain. On most boats, that means inside the console, under a helm seat, or in a dry electronics compartment above the bilge line.

Route the transducer and network cables away from high-current wiring when possible, and support the run so vibration and steering movement do not work-harden the cable at the connectors.

Electrical and system integration

Power the module from a clean 12V or 24V feed, keeping voltage drop low under load. The supplied power lead is 9 ft (2.7 m); when extending, use 10 AWG up to 15 ft (4.6 m) of extension, 8 AWG up to 23 ft (7 m), or 6 AWG up to 36 ft (11 m).

On the network side, connect the module to your Garmin Marine Network using the included cable and the included adapter cable when your chartplotter uses the larger network connector style.

Maintenance and care

Periodically check that the power and network connectors stay fully seated and dry, especially after heavy washdowns or trailering. If the boat lives in a salt environment, a quick wipe-down around the module and cable runs helps keep salt buildup from migrating into connectors over time.
