1. A portable communication apparatus comprising:
- a communications unit that communicates with a vehicle navigation system that is installed in a vehicle, the vehicle navigation system including a first Global Positioning System (GPS) unit and an electric compass;
a storage that stores plural sets of icon data where each of the plural sets of icon data correspond to a predetermined range of an azimuth angle, respectively; and
a display unit which displays, according to positional information that is detected by the first Global Position System unit of the vehicle navigation system and received through the communications unit from the vehicle navigation system, an icon which represents a position and a direction of the vehicle on a map based on one set of icon data, selected from the plural sets of icon data stored in the storage, according to an azimuth angle data that is detected by the electronic compass and received through the communications unit from the vehicle navigation apparatus;
the portable communications further including a second Global Positioning System Unit,wherein the communications unit transmits information acquired by the second Global Position System unit of the portable communications apparatus to a position information center, andwherein the display unit receives peripheral map information created in the position information center based on the information acquired by the second Global Position System unit of the portable communications apparatus and the information on the position and the direction of the vehicle measured by the vehicle navigation apparatus and displays on the display unit an icon showing the position and the direction of the portable communications apparatus and the icon showing the position and the direction of the vehicle navigation apparatus.

Abstract
A cellular phone places a call to vehicle navigation apparatus, performs ID matching, and acquires the information on the position of the vehicle measured by the vehicle navigation apparatus. The cellular phone acquires peripheral map data including the position of the owner of the vehicle and the position of the vehicle where the vehicle navigation apparatus is mounted from a position information center and displays the data acquired together with the data on the positions.
