A cellular phone receives an incoming call from a communication network in a state where an in-vehicle navigation apparatus cannot execute a handsfree control relative to the incoming call. If a permission for a notice of an incoming call is set, a display device displays information of "under an answer suspension state" indicating that an answer to the relative incoming call is being suspended. A user can recognize via the navigation apparatus that an answer to an incoming call is under the answer suspension state, thus concentrating on driving operation without need of manipulating the cellular phone to respond to the incoming call.
