If you have been using TwoNav 5 in the old Premium App (now discontinued), when switching to TwoNav 6 you will need to transfer your routes as they do not transfer automatically. This is because both versions are installed in different folders, so TwoNav 6 will not 'find' in its folder the tracks you had saved in the TwoNav 5 folder.

Procedure

To transfer your tracks from one version to another, we will use the TwoNav Cloud storage cloud as a bridge.

1. Activate synchronization with TwoNav Cloud in the TwoNav 5 app by tapping ‘Main Menu > Settings > TwoNav Cloud’. 
2. By doing so, all your tracks will be automatically uploaded to the cloud.
3. Once they are uploaded to the cloud, from the TwoNav 6 app, you must download them by tapping ‘Main Menu > Routes > More options > My routes online’.
4. Once inside, you can download routes individually or entire folders.
