Overview

The Garmin 010-C1185-00 is a preloaded microSD/SD electronic chart card for Mississippi Sound. It adds detailed regional mapping with a coastal aerial overlay that uses high-resolution imagery, plus local waterway and land feature names so it is easier to confirm where you are when you are close to shore.

This card also calls out fishing and management boundaries that matter in this area. Oyster leases are outlined in white, artificial reefs are marked with a white dot, and state and federal offshore boundaries are shown so the changeover is obvious when you are running the passes and heading out.

Key features

• Preloaded Standard Mapping Professional coverage for Mississippi Sound on a microSD/SD chart card
• Coastal aerial overlay with high-resolution imagery to help line up shoreline features with what you see on the water
• Local waterway and land feature names shown directly on the chart
• Oyster lease areas outlined in white for quick recognition while planning routes and drifts
• Artificial reefs identified with a white dot for faster spot checks on screen
• State and federal offshore boundaries displayed to make transitions clear
• Outlined Wildlife Management Areas and Offshore Lease Areas for added context in the region

Compatibility and fit

This is a Garmin chart card and it is meant for compatible Garmin chartplotters that read microSD/SD mapping cards. Confirm your display has the correct card slot type before ordering, and verify your unit is set up to read external chart data from the card.

Installation and setup

Power the chartplotter down, insert the card fully into the chart slot, then restart the unit. Give it a moment to index the card, then select the chart source if your plotter allows multiple map sources. When you remove the card, do it with the unit powered down and keep the contacts clean and dry.

Use on board

For skippers who spend time in Mississippi Sound, this mapping is especially helpful when you want oyster lease outlines, artificial reef markers, and offshore boundary lines visible alongside aerial shoreline imagery. It is a practical match for inshore runs, coastal cruising, and fishing days where quick confirmation of zones and marked areas saves time.
