Abstract

PROBLEM TO BE SOLVED: To provide a navigation device which displays only necessary VICS information to achieve a legible display by not displaying VICS information other than VICS information for a traveling route of one's own vehicle. SOLUTION: The navigation device, based on the received result of a VICS receiver 19 and a GPS receiver 5, determines whether the VICS information is related to a predetermined traveling route of one's own vehicle by a CPU 10. When the VICS information is determined to be related to a traveling route of one's own vehicle, only the VICS information on the traveling route of one's own vehicle is displayed on a liquid crystal display 8a.
