2. Description of the Related Art Conventionally, vehicle-mounted navigation devices that provide route guidance according to a user's operation input have been widely used.
The in-vehicle navigation device that provides such route guidance is
When the user inputs the destination and transit points, GPS
(Global Positioning System) etc. are used to recognize the current position of the vehicle, and the optimal route from the current position of the vehicle to the destination through the waypoint entered by the user is selected,
The route is guided while the necessary map is displayed on the display.

In such a vehicle-mounted navigation device, a method for a user to input a destination and a waypoint is as follows.
For example, a user can scroll through the map displayed on the display to search for destinations and stopovers, specify the destinations and stopovers on the map, and display a list with the names of major points. In general, a method of displaying a desired destination or a waypoint from the list and selecting the desired destination or transit point from the list.

However, the above method compels the user to perform a complicated operation, which increases the burden on the user. For this reason, various proposals have been made for an in-vehicle navigation device that provides route guidance, which makes it easier to input a destination and a waypoint and reduce the burden on the user. For example, Japanese Patent Laid-Open No. 5-241507. In the official gazette, a bar code corresponding to position information indicating major intersections and tourist attractions is printed on a map book, and the bar code scanner connected to the vehicle-mounted navigation device reads the bar code printed on the map book. Therefore, a technique for inputting a destination and a waypoint is disclosed.
