Overview

The Garmin Navionics NSUS012R is an electronic chart region for Canada, East and the Great Lakes that loads on compatible Garmin chartplotters. It combines coastal and inland coverage in one chart set, with Nautical Chart and SonarChart layers available for everyday navigation and contour-focused fishing. You get up to 1 ft contours, plus depth range shading with up to 10 color options so target depths are easier to spot at a glance.

The included one-year subscription unlocks daily updates through the ActiveCaptain app and supports Auto Guidance+ route suggestions using your entered depth and overhead clearance. Auto Guidance+ is a planning tool only and does not replace safe navigation. This region is a good match for crews running the Great Lakes, the St. Lawrence River and nearby coastal routes who want current chart data and clear depth presentation at the helm.

Variants

This chart region is offered in multiple configurations that vary by chart version and delivery format.

Garmin Navionics+ includes the core chart layers, depth shading and Auto Guidance+. Garmin Navionics Vision+ includes everything in Navionics+ and adds additional view layers such as high-resolution relief shading, satellite imagery, aerial photography and 3D views where available. Both card and download formats include a one-year subscription for daily updates through the ActiveCaptain app.

• 010-C1484-20: Version Garmin Navionics+ in microSD/SD format. A physical card plugs into the chartplotter card slot and stays installed for normal use on board.
• 010-D2231-20: Version Garmin Navionics+ in Download format. Map data is loaded onto your own microSD/SD card using Garmin Express, which is useful when you want to manage storage yourself.
• 010-C1484-00: Version Garmin Navionics Vision+ in microSD/SD format. This adds premium chart views on top of the standard layers while keeping a simple, plug-in card install.
• 010-D2231-00: Version Garmin Navionics Vision+ in Download format. This delivers the Vision+ content as a download so it can be written to your own microSD/SD card through Garmin Express.

Compatibility and fit

Confirm that your Garmin chartplotter supports Garmin Navionics+ or Garmin Navionics Vision+ for the region you are buying. You will also need an available microSD/SD card slot at the display for card use, or a microSD/SD card you provide if you are purchasing the download format.

Installation and setup

For the microSD/SD option, insert the card into the chartplotter card slot and leave it installed while underway. For the download option, use Garmin Express to load the charts onto your own microSD/SD card, then insert that card into the chartplotter.

Daily updates are handled through the ActiveCaptain app after activation. If you prefer updating on a computer, chart updates can also be applied to a card using Navionics Chart Installer with a card reader.

On-board use notes

Auto Guidance+ can help with route planning, but it should always be cross-checked against conditions, local knowledge, notices and your sounder. When updating charts, avoid removing the card or powering down the system mid-update, and keep card slots closed at the helm to reduce salt spray and moisture exposure.
