Not for sale as a separate product, Silver has been specifically designed to be bundled with select chartplotters to provide out-of-the-box usability with an enhanced basemap.
Silver includes coastlines, drying lines, navigation aids, and depth information up to 10 meters (30 feet).
Silver charts cannot be updated through Freshest Data. If you have a Silver card, you can upgrade it to Navionics+ online by clicking the “Upgrade your chart” button below or by purchasing a Navionics Updates card from a dealer. Either way, you get Navionics+ at half price: Nautical Chart, SonarChart™ HD bathymetry map, Community Edits and one year of free daily updates.
See the cartography you can upgrade to right now on our free WebApp.
You can also download the Navionics Boating app on your mobile device to view the same charts!
