Abstract

An on-board navigation apparatus in which one of a plurality of service facilities displayed on a display is designated by an operator input, the position coordinate data corresponding to the designated one service facility is registered as a user position into a memory. When the map is displayed on the display, the position coordinate data which has been user position registered is read out from the memory. The position on the map indicated by the position coordinate data is multiplexed onto the map by a predetermined pattern and displayed on the display. The positions of the service facilities such as restaurants, hotels, or the like, which are necessary for each user, consequently, can be easily confirmed on the displayed map.

Claims

1. An on-board navigation apparatus to display a map on a display, comprising:

first memory means for storing display data indicative of a plurality of service facilities, display pattern data indicative of multiple classifications of the respective service facilities, and position coordinate data indicative of existing positions of the service facilities;

means for reading said display data from said first memory means in accordance with an operator input and for displaying said plurality of service facilities onto said display in accordance with the read display data;

means for selectively designating one of said plurality of service facilities displayed on said display in accordance with an operator input;

means for reading the display pattern data and position coordinate data corresponding to the designated one service facility from said first memory means for every time a service facility is designated;

second memory means for storing the read display pattern data and position coordinate data corresponding to all of said display pattern data and said position coordinate data from said first memory means;

means for reading the stored display pattern data and position coordinate data from said second memory means when a map is displayed on said display; and

means for multiplexing the position indicated by the read position coordinate data from said second memory means onto the map by a display pattern corresponding to the read display pattern data from said second memory means in order to display on said display.

2. An on-board navigation apparatus according to claim 1, wherein said second memory means has a plurality of memory locations to store said position coordinate data and said position display pattern data to indicate said display pattern as a pair.
