Overview

The Garmin 010-C1188-00 is a Gulf Coast Standard Mapping Professional chart card for compatible Garmin chartplotters, supplied on a preloaded microSD/SD card.

It adds a sectioned coastal aerial overlay with local waterway and land feature names, plus map layers that call out Offshore Lease Areas and Wildlife Management Areas. Offshore field lease blocks are shown with red outlines and white labels, a marsh highway system is marked with yellow lines, oyster leases are outlined in white, artificial reefs are identified with a white dot, and state and federal offshore boundaries are shown for clear transitions offshore.

Key features

• Preloaded microSD/SD chart card for Garmin chartplotters that read Garmin cartography cards

Compatibility and fit

This is cartography for a chartplotter, not a network module and not an app download. Your display must accept a microSD or SD chart card and support Garmin chart cards to read the data.

If your boat has more than one helm station, each chartplotter reads its own card slot. Plan on where the card will live so the mapping is available on the screen you run most often.

Installation and setup

Insert the card into the chartplotter card slot, then power the unit on and select the chart source from your chart or map settings. Once the card is recognized, enable the aerial overlay and any additional layers you want to see so the screen stays readable at your typical zoom levels.

For best results around the coast and in the marsh, use the overlay as a visual reference alongside your regular chart view, then confirm your route with soundings, markers, and local conditions.

Use cases on board

This mapping is a good match for anglers and captains running shallow coastal routes, threading marsh passes, or working around reefs and offshore lease blocks where quick visual cues matter. It is also helpful when you want local names and clearly drawn boundaries on the screen while planning a run or setting up a track.

Care and handling

Keep the card and contacts clean and dry, and avoid handling it with wet or salty hands. When you remove it, store it in a protected case so the contacts do not get scratched or corroded.
