Abstract
An in-vehicle navigation apparatus to support sharing of electric vehicle charging point information such that other electric vehicles can use a charging point where its own electric vehicle is charged. If the in-vehicle navigation apparatus determines that a current position is a charging point on the basis of charge information about an electric vehicle, the navigation apparatus determines whether the charging point has public availability by referring to facility information, such as facility positions in map data stored in a map data storage unit. The in-vehicle navigation apparatus may transmit charging points having public availability to a server apparatus and not transmit the charging points having no public availability to the server apparatus. Vehicles may download charging points uploaded by other vehicles.
