PURPOSE:To guide a route change point more in detail. CONSTITUTION:As for an intersection and a branch where a route is possibly changed, modification contents determined by an entry path and an exit path, e.g. modification information showing 'entrance ramp' is stored on a CD relatively to route change points. When a vehicle approaches the route change point, modification information corresponding to a combination of an entry path and an exit path derived from a predetermined route is read out of the CD by a route guidance part 13 and outputted to a display device 8 and a speech output device 9. |
