A detail information extracting part 14 extracts the detail information contained in the traffic information stored in the traffic information memory 12, and stores the extracted detail information in a detail information memory 15. A display control part 16 displays, on a display part 5, one detail information obtained from the detail information memory 15 together with a change-over switch, when the detail information are stored plurally in the memory 15. When the change-over switch is touched via an operation part 6, the next detail information is read out from the memory 15 and the detail information is switched to be displayed on the display part 5. |
