cnc filling station in Europe

 

Ciao!
I'm a new member of the community, and I'm asking for your help: I have to go from milano, Italy yo Hannover, Germany using a experimental car filled with a mix of hydrogen and natural gas, at the moment there are few "Hytane" filling station, so I have to use simple CNG.
Where can i find Swiss and Germani maps for Garmin with CNG locations?
Grazie
Marco
