A geographical information database storing location information for a plurality of points of interest and a plurality of roadways is provided and a charging status of a vehicle is detected. When the charging status of the vehicle indicates that the vehicle is charging, a location of the vehicle is recorded. The location of the vehicle when the charging status of the vehicle indicates that the vehicle is charging is used to update a location of a charging station within the geographical information database.
