Overview

The Garmin BlueChart g3 Vision HD VEU457S Bretagne is an electronic chart for navigating the Brittany coast, covering from Saint-Vaast-la-Hougue to Le Croisic and Belle-Ile, including Cherbourg, the Channel Islands, Saint-Malo, Brest, and Lorient.

It is made to run on compatible Garmin chartplotters and adds chart layers that help with day-to-day coastal piloting, harbor work, and route planning. Features include Auto Guidance route suggestions (based on the depth and overhead clearance you enter), Depth Range Shading with up to 10 depth ranges, Shallow Water Shading, detailed 1 foot contours, and high-resolution satellite imagery.

Key features

• Regional coverage for Bretagne from Saint-Vaast-la-Hougue to Le Croisic and Belle-Ile, including major ports and approaches like Cherbourg, Saint-Malo, Brest, and Lorient
• Auto Guidance route suggestions that use your entered depth and overhead clearance for planning on supported plotters
• Depth Range Shading with up to 10 depth ranges to quickly highlight your target depths
• Shallow Water Shading you can set to match the draft and comfort margin you run
• Detailed 1 foot contours for a clearer picture of bottom shape and tighter contouring around channels and structure
• High-resolution satellite imagery for visual reference in familiar areas and when confirming shoreline features

Variants

This chart is offered in more than one format so you can match how you load charts on your boat.

The chart coverage and feature set remain the same, while the delivery method changes between a physical card and a computer-based download that you install to a microSD or SD card.

• 010-C0801-00: Format microSD/SD. A physical card you insert into the chartplotter, which keeps setup simple when you want a ready-to-use chart at the dock.
• 010-D0399-00: Format Download. Installed to a microSD or SD card using Garmin Express on a computer, then moved to the chartplotter for use underway.

Compatibility and fit

This is chart media, not a standalone navigation app. It requires a compatible Garmin chartplotter that supports BlueChart g3 Vision. If your display has more than one card slot, confirm which slot is used for cartography so the chart loads as expected.

Chart features such as Auto Guidance and shading layers depend on the chartplotter model and settings. For planning, enter realistic draft, safety depth, and overhead clearance values that match your boat and the way you operate.

Installation and setup

For the microSD/SD option, insert the card into the chartplotter while the unit is off, then power up and select the chart from the chart menu. For the download option, you will need a computer and a microSD or SD card for the chart install, then insert that card into the chartplotter.

Only one chart can be installed to a single microSD or SD card, so keep a dedicated card for this region if you also carry other chart regions on board.

Use on board

This chart makes sense for skippers who cruise Brittany and the nearby Channel approaches and want extra detail for coastal passages, harbor entrances, and day hops between ports. It is also a good fit for fishing and diving crews who spend time working contours and structure, since 1 foot contouring and depth shading make it easier to read bottom changes at a glance.

Auto Guidance provides a suggested route, but it does not replace good seamanship. Keep local notices, tides, and real-time conditions in mind, especially around drying areas, strong currents, and shifting bars common in this region.
