An in-vehicle handsfree apparatus stores a mail operation state while a message access profile (MAP) is being connected with a cellular phone. An incoming voice call from a communication network arises in the cellular phone while the in-vehicle handsfree apparatus is receiving mail information from the cellular phone. When the cellular phone answers the incoming voice call, the MAP is disconnected from the cellular phone. After completing the handsfree call relative to the incoming voice call, the reception of the mail information is resumed from the state just before the MAP was once disconnected.
