I have an older version of the app, how can I update with the latest available version?

From iOS device, go to App Store > Profile > Updated recently > Air Navigation Pro > Update
Also, by searching Air Navigation Pro in the App Store, simply tap Update.

For Android devices, go to the Play Store > Profile > Manage apps and device > Overview > Updates > Update Air Navigation Pro
Also, by searching Air Navigation Pro in the Play Store, simply tap Update.

If it doesn't allow you to download the latest version, make sure that your OS version is supported. Otherwise, you need to update the OS version first.

Always remember to log in to your registered account.
