An on-vehicle information terminal includes: a current position detection section for detecting a current position of a vehicle; a route setting section for setting a route from the current position of the vehicle detected by the current position detection section to a destination; and a display control section for displaying on a screen an enlarged map of the vicinity of the next guide intersection on the route set by the route setting section. The display control section displays the current position and the next guide intersection in a single screen of the display device and represents the route between them as a straight line, thereby displaying the enlarged map on the screen.
