ABSTRACT:
A vehicle information communication system determines whether or not an identifier code such as a telephone number is different from that currently registered in a vehicle-equipped information communication system wherein the vehicle belongs to a group of previously registered telephone numbers when a portable telephone having such telephone number is connected thereto, then considers that another portable telephone of a regular user is connected thereto if such telephone number belongs to the group, and then transmits such telephone number of another portable telephone to an information center. The information center can automatically update the currently registered telephone number to a new telephone number when it receives the new telephone number. Accordingly, a vehicle information communication function can be used by a user in a similar manner when the user who has a plurality of individual portable telephones uses the same vehicle.
