Overview

The Garmin BlueChart g3 Vision HD VUS003R (Cape Cod) is an electronic chart for compatible Garmin chartplotters, covering the waters from Gloucester through New London. The coverage includes Narragansett Bay, Block Island, Martha's Vineyard, Nantucket Island, the entire Cape, and general coverage of Georges Bank.

It combines Garmin and Navionics data and adds chart layers that help with real decisions on the water, including Auto Guidance route suggestions based on your entered depth and overhead clearance. You also get relief shading and contour detail down to 1 foot where available, which is useful when you are watching structure, edges, and shallow spots near the Cape and islands.

Key features

• Cartography built from integrated Garmin and Navionics data
• Auto Guidance route suggestions use your preferred depth and overhead clearance settings
• Relief shading helps separate bottom structure and changes in terrain at a glance
• Contour detail down to 1 foot where available for better bottom definition
• Depth Range Shading supports up to 10 depth ranges so you can highlight a target depth band
• Satellite imagery and aerial photos add visual context around ports, marinas, bridges, and landmarks where available
• 3D chart views are available on chartplotters that support those view modes

Variants

This chart is offered in multiple formats so you can match how you prefer to load mapping onto your system.

The format is what changes between versions. Coverage and chart content are tied to the VUS003R Cape Cod region, while some advanced views and layers depend on what your chartplotter supports.

• 010-C0704-00: Format microSD/SD. This is a physical chart card for chartplotters with a compatible card slot, which is handy when you want to move the card between displays on the boat.
• 010-D0534-00: Format Download. This version is downloaded to a memory card using Garmin Express, then used in the chartplotter like a chart card.

Compatibility and fit

This cartography is intended for Garmin chartplotters that support BlueChart g3 Vision mapping. Before buying, it is worth confirming your chartplotter model supports g3 Vision features, since some layers like 3D views and certain imagery can vary by device.

If you are using the card format, make sure your display has the right card slot for the included media. For the download format, plan on using a compatible microSD or SD card in a computer to load the chart, then insert that card into the chartplotter.

Installation and setup

For the microSD/SD version, install is straightforward: insert the card into the chartplotter and select the chart layer from your mapping page. For the download version, use Garmin Express to load the chart to a memory card, then move that card to the chartplotter for use onboard.

Once loaded, set your depth and overhead clearance preferences before using Auto Guidance so the suggested paths reflect your boat and the conditions you run in.

Use on board

This region is a good match for skippers who run the Cape and island routes regularly and want more context than a basic basemap gives, especially when planning routes around shoals and tight approaches. It also suits anglers who rely on contour detail and shading to spot edges and structure without spending time bouncing between different chart screens.
