Once you have purchased a region of coverage within the Navionics® Boating app, chart updates are released daily. Your purchase offers a subscription for chart updates and advanced features. If updates are available for charts you have already downloaded, you will see the offer to update as a banner notification at the top of the screen. Alternatively, you can use the Update Maps button in the app Menu.
You will receive update notifications through the store on your device when an updated version of your Navionics app is available.
IMPORTANT: Logging out and logging in with a different account will erase the previously downloaded charts related to discontinued or expired subscriptions. Upon new installation of the Boating app to a device, chart downloads and updates can only be performed when a subscription is active.
To set up automatic updates go to the Google Play Store app and then tap your Profile Icon > Settings > Network Preferences > Auto Update apps.
