Head out with confidence, knowing you have the latest data on your Garmin Navionics+™ and Garmin Navionics Vision+™ charts. We improve the cartography daily with new public and private data sources, proprietary surveys and notices to mariners — so you have up-to-date shorelines, depths, on-shore POIs, buoy, light and obstacle locations and more. Check the heatmap to see where we’ve made updates around the world. Updating is easy with either the ActiveCaptain® app or Garmin Express™ software.
