A multi-display system according to the present invention includes: first display means for displaying a plurality of first windows; second display means; and control means for controlling the first display means and the second display means. In response to a first predetermined input, the control means moves at least two of the plurality of first windows displayed on the first display means from the first display means onto the second display means.

Branch-point image data has coordinates added thereto according to the distance from a branch point such as an intersection. When the vehicle is within a predetermined distance from a branch point on a suggested route, the coordinates of the present position of the vehicle and the coordinates added to the branch-point image data are compared to locate the present position on the image data, and a present-position mark is displayed superimposed on the branch-point image data. The displayed present-position mark moves according to the distance between the vehicle and the branch point.

Navigation system and storage medium

Map data is divided into meshes of a prescribed size. Treating four meshes as one group, mesh numbers are assigned to the meshes following an N pattern. After numbers are assigned to the four meshes, these four meshes are collected as one, and numbers are assigned to respective meshes following an N pattern. The map data storage medium stores the map data according to mesh number. As a result, data portions for areas located in close proximity are positioned in close proximity in the map database (storage medium), to thereby improve access efficiency.

Map data storage medium

A navigation device at least includes a CPU and a detector generating a detection signal for determining whether a main device is used inside a vehicle or not. If determining, based on the detection signal from the detector, that the main device is used inside the vehicle, the CPU operates in on-vehicle mode to carry out first navigation (present position estimation and route search) suitable for use in the vehicle. Otherwise, the CPU operates in off-vehicle mode to carry out second navigation (present position estimation and route search) suitable for use outside of the vehicle. Thus, the navigation device can automatically switch its operation mode between on-vehicle mode and off-vehicle mode.
