PROBLEM TO BE SOLVED: To provide a navigation apparatus which can be easily changed over to a road map of a map display type and scale ratio meeting crew's preference. SOLUTION: The words specifying the map display type and scale of the road map displayed on a display monitor 16 are stored together with the map display type and the scale thereof as map display changeover data in a memory section 111. When the road map displayed on the display monitor 16 is desired to change over to the road map of the desired map display type and the scale, the crew utters the words to specify the map display type and scale toward a microphone 19 while depressing a PTT switch 19a provided at the microphone 19. The map display type and the scale stored in the map display changeover data are read out by the words uttered by the crew. The road map of the display monitor 16 changes over to the data of the map display type and the scale. COPYRIGHT: (C)2008,JPO&INPIT |
