US Patent 7636634 On-vehicle information terminal

An on-vehicle information terminal includes a current position detection unit that detects the current position of the subject vehicle, a route setting unit that sets a route from the current position of the subject vehicle detected by the current position detection unit to a destination and a display control unit that displays at a display device an enlarged map around the next guidance-requiring intersection on the route having been set by the route setting unit. The display control unit displays the enlarged map by displaying the current position and the next guidance-requiring intersection in a single screen at the display device and rendering the route between the two points as a straight line.
