The map component is not working in Germany, as the latitude and longitude values in final link to virtualearth.net are formatted with commas as the decimal separator.

This won't work. But by replacing the commas with dots, everything works fine. You can do that in code like this:

Substitute(Text(Latitude);",";".")

for every Latitude, Longitude and Map.Latitude / Map. Longitude value in imgMap, imgMapCache1 & imgMapCache2 controls of the reusable component.
