PROBLEM TO BE SOLVED: To enable a driver to smoothly change a guiding route to another in a period of running, without deviating from the guiding route. SOLUTION: At the time of deviation from the guiding route (S39), a plurality of routes from the current place to the destination are searched (S42), and the driver is made to select one of them as the guiding route. When the guiding route is decided by the selection of the user (S44), guidance to the destination is started based on this guiding route (S47). During the running without deviation from the guiding route, the other searched routes and also route selection buttons are displayed on a map, together with the searched guiding route, in a screen of a touch-screen type display part 27 (S48). On each selection button, information about a needed distance, needed time, etc. as to a route corresponding to the button is indicated. When the driver pushes the selection button (S49), the guiding route is changed to the corresponding route and then a return to route guidance (S47) is made. COPYRIGHT: (C)2010,JPO&INPIT |
