Abstract
In a vehicle navigation system, when a voice control part, which is displayed on a screen, is switched off, a voice control part inhibits voice guidance from being output to a speaker. Now, if a current-location/guide selection key is operated, the voice control part creates voice guidance according to the operation of the selection key and outputs the voice guidance from the speaker. With this navigation system, aural route guidance is possible only at the driver's request.
