PROBLEM TO BE SOLVED: To solve the problem that the path travel history information on a navigation apparatus with the travel assistance of a mobile unit as a purpose can be reutilized less, and the information cannot be effectively utilized in other pieces of equipment or people other than a user. SOLUTION: The navigation apparatus stores path travel history information in a non-volatile memory where the information can be read. Other pieces of navigation apparatus are allowed to read the path travel history information from the non-volatile memory, thus reutilizing the path travel history information. Additionally, the path travel history information that is stored in the non-volatile memory is corrected/edited by the navigation apparatus or on a personal computer, thus improving reutilization properties. |
