I don’t understand why the export for Navigon devices was dropped.
One of the reasons why I have supported this platform for years is (was) the easy export to Navigon.
Now I have to go through the hassle of converting the files with other programs — extra steps and extra sources of error.
The Navigon export was dropped because we completely rebuilt the export functionality. Every single file format would have had to be re-engineered, and the Navigon export was almost entirely unused. That’s why it wasn’t converted to the new system.
Every navigation system calculates routes individually using its own algorithms, settings, and map/road data. Put simply: a 1:1 identical route can only ever be reliably guaranteed using the exact same system.
If you don’t want to navigate with your smartphone, you can also use Kurviger with Android Autoor Apple CarPlay. That might be worth considering.
