摘要：
A navigation apparatus acquires geographic information from a server apparatus. When the navigation apparatus does not store any geographic information that provides a continuous route from the starting point to a destination point, it transmits data of the starting point and destination point to the server apparatus to acquire therefrom geographic information that provides a continuous route from the starting point to the destination point. This efficient acquisition of geographic information realizes reduction of communication time and communication costs.
