string getGeodeticCoordinates(string x, string y)

This method takes input coordinates (x, y) in the Exchange Coordinate System and transforms them to geodetic coordinates in the map's datum.  

This method should not be used unless the map's coordinate system is of type NEMR or LLDG (See Map Types).  One of two possible transformation types is performed: geodetic to geodetic or projected to geodetic, depending on whether the Exchange Coordinate System is geodetic or projected, respectively.

The returned string is a comma-separated pair (Lon, Lat) in CARIS standard format (See Standard Geodetic Strings).
