PROBLEM TO BE SOLVED: To support a user in finally deciding the destination by proposing a candidate of the destination to the user from the side of a navigation apparatus. SOLUTION: When a proporsal request instruction is given by a user (S10: YES), a database is acquired according to a season at this point of time (S50). For example, when the season is summer, a skiing ground is not contained. In addition, when the weather is rainy (S60: YES), only proper destinations even in the rainy weather are picked up (S70). Then, an anticipated arrival time up to every destination is computed. When the anticipated arrival time is later than the prescribed time of a business finish time, the destination is excluded from a candidate. That is to say, when the destination cannot be used sufficiently even when it is reached too late, it is substantially meaningless as the candidate. The candidate which is extracted in this manner is displayed. When the user selects the destination, a route up to the selected destination is computed, and the route is guided. |
