Hi Petr, as said above I am doing the same sort of thing although I am searching for the nearest road from a point so I can get a postcode.
The Map.ObjectsFromPoint method:
Code:
mpResults := mpMap.ObjectsFromPoint(mpMap.LocationToX(mpLocation), mpMap.LocationToY(mpLocation));
The above converts the Given location to a X,Y point on the Map it then searches for any Nearby Objects, roads, places of interest, towns etc..
