Note: when using the free version of Avenza Maps, you are limited to using 3 imported maps at a time. You can download all 14 CSI maps to Dropbox or another file storage location, but only 3 can be imported to the Avenza Maps app. You can delete maps if you need to make room to import another.

  • Move downloaded map files to your Dropbox folder.

  • You can keep the map oriented with North “up” or have the map rotate as your heading changes (“Follow-mode”).
  • Note: if your current position does not fall within the map coverage area you will see the words “Not on map” where the coordinates display.
