Document Type and Number:
Japanese Patent JP4361595
Kind Code:
B2
Abstract:
A navigation device provides route guidance only by voice guidance even if route guidance by a display screen is impossible. A navigation device displays on a display device a navigation screen including a map about a current position. The display device can enter a no-display state. In the navigation device, regardless of the state of the navigation screen, a route guidance method is performed. More particularly, in the display state, a guidance route is determined by a normal mode and route guidance is performed by both voice and display. In the no-display state, a guidance route including fewer movement methods is determined and route guidance is made only by voice guidance. Thus, in the no-display state where the navigation screen is not displayed, a guidance route is determined so as to enable route guidance only by voice.
