Description

[Detailed description of the invention] Technical field The present invention relates to an in-vehicle navigation device.

BACKGROUND ART In-vehicle navigation devices have recently been developed in which the current position and destination of the vehicle are shown on a map displayed on the screen of a display device such as a CRT (cathode ray tube) display. In such in-vehicle navigation devices, the destination can be set simply by moving a cursor on the screen of the display device, but it can also be done in a short time by inputting related information such as place names and leisure facilities. It is desirable to make this possible. Therefore, a list of place names, a list of leisure facilities, etc. corresponding to the map displayed on the display device can be displayed, and related information can be input by the user's selection of the place name, leisure facility, etc. in the displayed list. It is possible that At this time, it is preferable to obtain the map, list of place names, list of leisure facilities, etc. from an external storage device with a large storage capacity, such as a CDROM, i.e., a digital audio disk, as a disk for digital data, in order to achieve miniaturization. . However, in this case, the access time of external storage devices is longer than that of solid-state storage devices such as semiconductor memories, so when attempting to set a destination using either the place name list or the leisure facility list, the number of items in the one is limited. Even if you try to display the other list when there are a lot of requests and it seems like it will take a lot of time, it will take time to switch to the other list, which is expected to cause an inconvenience in that it will take more time to set the destination.

SUMMARY OF THE INVENTION An object of the present invention is to provide an on-vehicle navigation device that can set a destination in a short time.

The in-vehicle navigation device according to the present invention stores at least two types of mutually related information in at least two storage means, and stores one of the two types of information in response to a command in the two storage means. It is configured to read and display from one side.
