If you have purchased the NAVIGON app via the App Store or iTunes, you will be able to install and use this via the App Store onto a new device (up to 5 devices simultaneously). To do this, it is necessary to use the same Apple ID on the new mobile device (Apple operating system) which was used with the initial purchase of the NAVIGON app. Transferring onto another operating system (iOS to android or WindowsPhone) is technically not possible!
Please note: The NAVIGON Select app (without in-apps) can be used free of charge for a 2 year period with iOS, android and WindowPhone. To continue using the app, it is necessary to purchase an in-app. The purchased in-apps are always bound to the app store of the respective operating system because of technical licensing reasons. This means, that if you have purchased in-apps from the App Store, then these are only available to restore to the respective app in that app store.
How to install the NAVIGON app onto a new device is explained here.
