ABSTRACT:
A portable communication device comprises a GPS module for determining the present position, an electronic compass module for detecting an azimuth, a display, and a wireless communicator. Herein, the position information representing the destination and present position is transmitted towards the navigation server, which in turn provides the map information including the destination and present position, based on which corresponding icon symbols are indicated in the map displayed on the screen. In addition, the azimuth is also indicated by an angle departing from a north direction of the map information. Specifically, an azimuthal arrow symbol is displayed in proximity to the icon symbol representing the present position in the map, or the icon symbol is inclined by the aforementioned angle. Thus, it is possible to create images for navigation that are appropriately displayed on the screen and are recognizable in viewing without using expensive graphic processing.
