A mover such as a vehicle acquires the information, which has been updated by broadcasting/communication during an engine stall or in an unreceivable state, after the engine start or the recovery of reception. The engine stall period and the unreceivable state continuation period of the mover are monitored and are notified after the engine start from a communication device to an information center and a mounted device. In response to this notification, the information center extracts the information, which has been updated during the engine stall period and the unreceivable state continuation period, and transmits the information to the communication device of the mover. As a result, the mover can always hold the latest information of a broadcast receiving device, the communication device and an information service device.
