Overview

The Garmin Navionics Bay of Biscay chart is an electronic chart package for compatible Garmin chartplotters, covering the Atlantic coast of Europe from Dunkirk, France to A Coruna, Spain, including the Channel Islands.

This region includes major ports and approaches such as Le Havre, Brest, Nantes, Saint-Nazaire and Bordeaux in France, plus Bilbao and Gijon in Spain. Contour detail can display up to 1 ft (0.5 m) where available, which helps when you are working structure for fishing or trying to read shoals and channels on coastal runs.

A one-year subscription is included for chart updates and downloadable content through the ActiveCaptain app. Auto Guidance+ can calculate a suggested dock-to-dock path using your set depth and overhead clearance alongside chart data and frequently traveled routes.

Key features

• Bay of Biscay coverage area: Atlantic coast from Dunkirk, France to A Coruna, Spain, including the Channel Islands and key French and Spanish ports
• One-year chart subscription included for daily updates and downloadable chart content through the ActiveCaptain app

Variants

This product is offered in two versions (Garmin Navionics+ and Garmin Navionics Vision+) and in two delivery formats (microSD/SD card or download).

All options cover the same Bay of Biscay region; the difference is the chart feature set between Navionics+ and Vision+, and whether you want a physical card or a digital download workflow.

• 010-C1235-20: Version Garmin Navionics+; Format microSD/SD. A physical card fits plotters that accept microSD or SD media and is straightforward to move between compatible units.
• 010-D1837-20: Version Garmin Navionics+; Format Download. Download delivery avoids handling a card and uses the chart download and update workflow tied to your ActiveCaptain setup.
• 010-C1235-00: Version Garmin Navionics Vision+; Format microSD/SD. Adds extra visual layers such as relief shading and satellite imagery overlays, with 3D views and photos where available, while keeping the convenience of a card.
• 010-D1837-00: Version Garmin Navionics Vision+; Format Download. The premium Vision+ layers are delivered through a download workflow for chart management and updates through your ActiveCaptain setup.

Compatibility and fit

These charts are intended for use on compatible Garmin chartplotters. Before ordering, confirm your display supports Garmin Navionics+ and Garmin Navionics Vision+ cartography and that you have the right media slot (microSD or SD) if selecting a card format.

For route planning and depth-based features, make sure your boat profile settings on the chartplotter are current, including draft and any overhead clearance you want the routing tool to consider.

Updates and on-board use

With an active subscription, updates and additional chart layers are obtained through the ActiveCaptain app. Content downloaded during the subscription period remains available on your card or installed chart storage, but no new downloads are available after the subscription expires unless it is renewed.

This is a good match for skippers running Garmin electronics along the French Atlantic coast and northern Spain who want current chart detail for harbor approaches, coastal passages and structure-focused fishing.

Routing note

Auto Guidance+ route suggestions are for planning purposes only and do not replace safe navigation practices, local knowledge and prudent watchkeeping.
