する。Next, the operation of the above embodiment will be explained. The driver uses the input means 1 to input the current position of the vehicle and the limit value of the rate of change in the position of the vehicle on the displayed map. As a result, the display control means 5 reads the map data from the storage means 6 and displays a map around the current position of the vehicle on the display means 7. When the vehicle starts moving, the vehicle position detecting means 2 sends the vehicle position change information to the display control means 5. On the other hand, the speed calculation means 3 calculates the traveling speed of the vehicle based on the information from the vehicle position detection means 3 and sends the information to the magnification rate selection means 4. Based on this information, the magnification rate selection means 4 calculates the change in the position of the vehicle on the displayed map, and compares it with the limit value of the rate of change in the position of the vehicle initially set by the input means 1. When the change in vehicle position exceeds the upper limit value initially set by the driver, the magnification rate selection means 4 instructs the display control means 5 to display at a lower magnification rate. Further, if the value falls below the lower limit of the initially set limit value for a certain period of time, the magnification rate selection means 4 instructs the display control means 5 to increase the magnification rate. The display control means 5 reads map data from the storage means 6 based on this information and displays it on the display means 7.
