Garmin GSD 26 Replacement Terminal Lid

Overview

The Garmin 010-11823-00 is a replacement terminal lid for the Garmin GSD 26 CHIRP Professional Sonar Module. It restores the original cover over the GSD 26 terminal area, helping keep the connections protected from dropped tools, loose gear, and general grime when the black box is mounted under a helm, in a console, or inside an electronics locker.

This is a straightforward service part used when the original lid is missing or damaged after maintenance or a refit. It does not change wiring, sonar performance, or network settings; it is strictly the cover.

Packaged size is roughly 7 x 5 x 2 inches with a shipping weight around 0.3 lb, which can be useful when planning spares or consolidating shipments for multiple installs.

Key features

• Direct replacement terminal lid made for the Garmin GSD 26 sonar module
• Covers the terminal area to reduce accidental contact with wiring and help keep debris out
• Useful after service work or refits where the terminal cover is removed and can be misplaced
• Black finish to match typical GSD 26 hardware appearance
• Approximate packaged size 7 x 5 x 2 in; shipping weight about 0.3 lb

Compatibility and fit

Intended for Garmin GSD 26 CHIRP Professional Sonar Module installations. Because this is a model-specific cover, confirm your black box is a GSD 26 before ordering.

Installation and setup

Mounts in the same way as the original cover on the module. If you are working around power or signal connections, disconnect power to the sonar module before handling the terminal area, then re-secure the lid once wiring checks are complete.

Use on board

A good match for boats that keep the GSD 26 in a busy space such as an under-helm area, console, or rigging locker where loose gear and salt-laden air can reach exposed terminals. Keeping the terminal area covered also helps when multiple technicians or crew members access the compartment.

Maintenance and care

Wipe the lid with a damp cloth as needed. Keep the terminal area dry when the cover is off for service, and avoid leaving the module open during washdowns or when the boat is taking spray.
