When the selection key 3 is operated, the control unit 4 displays a prefecture name list on the display unit 6. FIG. 21 is an explanatory diagram showing an example of a prefecture name list displayed on the display unit 6. When the driver operates the selection key 3 to move the selection mark on the prefecture name list and selects "Osaka", the control unit 4 reads the place name list of Osaka from the storage unit 5 and displays it on the display unit 6. . The driver selects "Shin-Osaka Station" from the place name list by the same operation and finishes the setting of the place of departure. Next, by the same procedure, "Hiroshima" and "Hiroshima Station" are selected, and the destination name is selected. When the setting of the departure place name and the destination name is completed, the control unit 4 displays the traveling information such as the positional relationship between the departure place and the destination and the traveling direction on the display unit 6. When the vehicle starts traveling, the control unit 4 displays the current position and traveling locus of the vehicle on the display unit 6 in an overlapping manner based on the information from the traveling distance sensor 1 and the azimuth sensor 2.
