Amundsen Infotainment ( navigation)

I have a Scala SEL with the Amundsen  navigation.  It is pretty

useless,inflexible and overcomplicated compared to my TOMTOM 6500.

Does anyone know how to import routes.

I like to create my own routes using the "MyRoute" app.

Routes can be saved in many formats, including csv as used on the Skoda Rapid Sport ( neither rapid or sporty) which I owned previously.

Any help out there ??
