Abstract

Goals desired by a user are searched based on the search reference data that serve as reference for searching the goals, the order of priority of the goals is determined from a relationship between the data of goals and the data of a reference position, and the data of the thus determined order of priority are indicated. Even when the car is running, therefore, the user is allowed to easily select within a short time the goals that conform to his desire with reference to the order of priority. Accordingly, the user can devote himself to driving. When the goals are to be indicated, a map scale is so determined that the goals are indicated in a predetermined number or in a number not less than the predetermined number, and the goals are indicated on the map of this scale. Therefore, the scale of the map picture indicating the goals is automatically so adjusted, and can be easily discerned by the user. Therefore, the user is liberated from the need to manually adjust the reduced scale.
