During an off-state of an ignition switch, a reception circuit and a transmission circuit of a station for telematics services in a vehicle are periodically shifted between an on-state and an off-state. As soon as a door knob of the vehicle is manipulated during the off-state of the ignition switch, the reception and transmission circuits along with a control circuit are shifted into the on-state even when staying in the off-state thereof. Thereby, a user can be, without waiting, provided with the telematics services associated with interface circuits for controlling operations relating to a vehicle body. |
