Abstract
An in-vehicle apparatus includes: a memory for storing a map data; a center communication element for obtaining a latest map data from a center; an inter-vehicle communication element for communicating with another in-vehicle apparatus; an input element for receiving an input signal of a specific area from an user; and a controller for setting the specific area as an initial main area. The inter-vehicle communication element receives another map data from another in-vehicle apparatus. The controller compares the map data with another map data. When another main area includes an area not included in the initial main area, the controller adds the area as a new main area, and updates the map data with another map data. The controller updates the map data corresponding to the initial main area with the latest map data.
