Garmin Navionics+ Charts for U.S. and Canadian Waters — Navigate with Confidence from Coast to Coast
Garmin Navionics+ marine charts deliver some of the most detailed and regularly updated cartography available for recreational and serious boaters navigating U.S. and Canadian waters. Whether you're running coastal inlets along the Atlantic seaboard, trolling the Great Lakes, or picking your way through Pacific Northwest anchorages, these region-specific chart cards give your compatible Garmin chartplotter the depth contours, marina data, and navigational markers you need to move safely and efficiently on the water.
What Garmin Navionics+ Charts Bring to Your Time on the Water
- Plan routes through unfamiliar coastal passages — detailed shoreline mapping and port information help you prepare before you leave the dock, not after you're already underway.
- Fish more confidently on inland and offshore grounds — high-resolution depth shading and bottom contours let anglers identify structure, drop-offs, and flats that aren't visible on the surface.
- Navigate Great Lakes shipping lanes and anchorages — the U.S. North and Great Lakes chart card covers one of North America's most heavily trafficked freshwater systems with precision detail.
- Explore Gulf Coast and Southern waterways with local accuracy — the U.S. South chart card covers the intricate bayous, ICW segments, and offshore Gulf waters where conditions change quickly.
- Cruise Pacific coastal waters from Baja to the Salish Sea — the U.S. West chart card supports everything from harbor hopping to offshore fishing runs.
- Extend your range into Canadian territory — the Canada East and Great Lakes chart card bridges the border for boaters who cruise north of the St. Lawrence or into Ontario's lake country.
Choosing the Right Regional Chart Card for Your Home Waters
Each Garmin Navionics+ card covers a defined geographic region, so the most practical starting point is simply where you boat most. Boaters who stay within a single region — say, the mid-Atlantic coast or the Pacific Northwest — will find a single regional card covers their needs completely. Those who regularly cross regions, or who trailer their boat between coasts, may want to look at broader coverage options like the U.S. and Coastal Canada card, which spans both countries in one package.
All cards in this collection are designed as physical microSD/SD cards that slot directly into compatible Garmin chartplotters — no subscription streaming required once the card is installed. Check your chartplotter's compatibility before purchasing, as supported devices vary by model. If you're outfitting a new helm or upgrading an older unit, confirming compatibility with Garmin's device list first will save you a step.
