Navionics Boating: Downloading Map Detail and Overlays

Downloading Maps

Charts can be downloaded within the Navionics® Boating app during the initial free trial or during an active subscription.  

To download mapping on your device you will need an internet (Wi-Fi or Cellular) connection, then do the following:

1. Tap Menu.
2. Tap Download Maps.
3. A selection box will appear on the screen to select an area of mapping you would like to download. Use the pins on the corners of the selection box to adjust your area.
4. Choose the map layers you want to download. Nautical Chart and SonarChart are automatically selected.
5. (Optional) Tap the + symbol to select and download Navionics Satellite Imagery, Relief Shading, or Sonar Imagery (select US lakes only). Tap the X in the upper right to exit this option.
6. Tap the Download button to begin the download of charts.

Charts are also downloaded when panning and zooming on an area of interest when zoomed into the map at less than 1NM and an internet connection is available. The downloaded map is as large as the current screen.

Downloaded maps will appear highlighted and are stored on your device for use during your active subscription. To view highlighted areas of downloaded maps, your Overlays (Menu > Map Options) should be off (No Overlay).

Downloading Map Updates

During an active subscription you can update your maps by going through the steps above and downloading the mapping area again. To update all previously downloaded maps, go to Menu > Update Maps. You will receive an estimate of the additional space the updates will require, and you can tap the blue Update button to proceed or tap the Later link to cancel.
