ON-VEHICLE INFORMATION TERMINAL UNIT, ON-VEHICLE INFORMATION CONTROL SYSTEM AND ON-VEHICLE INFORMATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an on-vehicle information terminal, an on-vehicle information control system and an on-vehicle information control method, capable of keeping identity of information between an on-vehicle information terminal unit and a center device, even if a user executes deletion operation of contract information.

SOLUTION: When inputting a deletion command of registered user information from the on-vehicle information terminal unit 100, a cancellation command of the contract information is transmitted by being connected to the center device 200 of storing the contract information. Since the center device 200 executes cancellation processing of the stored contract information by receiving the cancellation command of the contract information, the identity of the information can be kept between the on-vehicle information terminal unit 100 and the center device 200 without being consciously connected to the center device 200 by the user.
