Garmin Flush Mount Gasket, For GMI 20, GNX 20/21, GNX Wind, GHC 20

Overview

The Garmin 010-12021-00 is a flush-mount gasket that lets compatible Garmin instrument displays sit flat in a helm or nav-station panel, with a clean gasketed edge around the bezel.

It is used when you want a flush or flat mount for a GMI 20 digital marine instrument display, GNX-series instrument heads, or the GHC 20 marine autopilot control unit, instead of leaving the unit surface mounted.

Because it is a mounting accessory only, it does not change wiring, networking, or power requirements; it simply handles the panel interface where small gaps tend to collect spray and grime.

Key features

• Flush-mount gasket for helm and console installations where you want the instrument to sit flat to the panel
• Fits Garmin GMI 20 and the GNX family, including GNX 20, GNX 21, and GNX Wind
• Also compatible with GNX Wireless Sail Pack 43, GNX Wireless Sail Pack 52, and GNX Wireless Wind Pack instrument heads
• Compatible with the Garmin GHC 20 marine autopilot control unit for a consistent flush install
• Sits between the unit and the panel to finish the cutout edge and reduce the visible gap around the bezel

Installation and setup

Dry-fit the unit in the panel opening first, then place the gasket between the instrument housing and the front of the panel before tightening the mounting hardware. Keep the gasket seated evenly so the bezel sits flat and the gasket is not pinched at the corners.

This part is most useful on boats where the dash sees salt spray or frequent washdowns, since a tidy panel interface is easier to keep clean.

Compatibility and fit

Compatible devices include Garmin GMI 20, GNX 20, GNX 21, GNX Wind, GNX Wireless Sail Pack 43, GNX Wireless Sail Pack 52, GNX Wireless Wind Pack, and the GHC 20 autopilot control unit.

Confirm your exact instrument model before ordering, since flush-mount gaskets are specific to bezel shape and mounting footprint.

Use cases on board

This gasket is a good match for boats that keep instruments on an exposed helm, in cockpit pods, or at a navigation station where you want a flush look and fewer edges to snag cleaning cloths and lines.

Maintenance and care

Rinse salt residue from the panel area during routine washdowns and avoid harsh solvents that can swell rubber gaskets. If you remove the instrument later, inspect the gasket for nicks and re-seat it flat before reinstalling.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
