@ leitz5138 Back to basics...
Autodrive is a standalone map that contains one country, Greece.
You cannot create a route from Austria to Greece using Autodrive, because there is no Austria in Autodrive map.
When using your Garmin device you must have ONLY ONE map checked, not many, especially if they cover the same area, like City Navigator Europe and Autodrive. If you have those two maps checked at the same time and you want to navigate from Austria to Greece, you cannot be sure which map's data will be used. CN Europe has a lot of countries that's why it asks for "Nation", Autodrive has just one, Greece and that's why it will never ask you for a "Nation".
