ABSTRACT:
The map updating system (100) includes a server unit (400) and a terminal unit (300, 300A,300B). The server unit (400) has an updated contents recognizer that recognizes updated contents of updated map information and generates updated contents information, a user recognizer that recognizes distribution request information and also recognizes user information containing the distribution request information when determining that the updated contents information contains request contents of the distribution request information, and an information transmitter that transmits the updated map information to the terminal unit (300, 300A,300B) corresponding to the user information such that the map information can partially be rewritten with a part of the updated map information. The terminal unit (300, 300A,300B) includes a terminal map updating section that acquires the transmitted updated map information and stores the part of the updated map information in a terminal storage section in a rewritable manner.
