PURPOSE:To make it possible to perform the route guiding with which the request of a driver agrees by detecting the entering a specific road whose entrances and exits are limited and performing a voice guide based on the entering of the specific road when a vehicle enters the specific road. CONSTITUTION:When the location of its own vehicle approaches a cross-point where a route should be changed, a display screen changes and displays the name of the cross-point and the distance to the cross-point. At the same time, a route guide control part 26 instructs a voice control part 30 to generate the voice corresponding to the route guiding at the cross-point. The voice control part 30 reads the information stored as digital data in a voice storage part 32, converts it into an analog signal and drives a speaker 34. By the speaker 34, the route guiding is performed by performing a route guide such as 'Turn to the left at the next cross-point'for a driver. Further, the entering of a specific road such as a toll road and an expressway is detected and the route guide according to this detection is performed. The judgment of the entering is performed by an entering detection part 26a of the route guide control part 26. |
