Navigation apparatus with enhanced positional display function.

摘要

A navigation apparatus has configuration including a position detector (4) for detecting a vehicle's position and outputting vehicle's position data, a memory (12) for storing map data, a display unit (17) for displaying a variety of information, and a display controller (14) for displaying a map on the display unit based on the map data and superimposing the vehicle's position on the map displayed on the display unit based on the vehicle's position data. The apparatus further includes a commander (11) for specifying an arbitrary position on the map displayed on the display unit; a coordinate calculator (7) for calculating the latitude and longitude as the coordinates of the actual location corresponding to the specified position on the map and outputting the same as coordinate data; and a coordinate display controller (14) for superimposing the coordinates of the actual location in numerical values on the displayed map based on the coordinate data. According to another aspect, a navigation apparatus comprises a second memory (9,12) for classifying location name data on a plurality of locations and coordinate data corresponding thereto according to the category of the locations, and storing the classified data; a location name display controller (14) for sequentially displaying the location names of the plurality of categories on the display unit (17) based on the stored location name data; and a commander (11) for selecting a desired location based on the location names displayed on the display unit. The map display controller (14) reads the map data around a location associated with the coordinate data corresponding to the location name selected by the selecting commander and displays the map based on the map data. <IMAGE>
