Abstract

A hands-free system, through which a driver communicates without using hands with an on-board mobile phone such as a cell phone, is mounted on an automotive vehicle. Plural speakers including a center speaker installed in an instrument panel and door speakers each installed in each door are mounted on the vehicle. Whenever the center speaker is mounted on the vehicle, the center speaker is selected as a speaker from which voices transmitted from the mobile phone are outputted. Only when the center speaker is not mounted, the door speakers are selected. When the center speaker is selected, the voices transmitted from the mobile phone can be heard from a direction to which a driver's eye line is directed. Accordingly, the driver is able to hear the speaker sounds from the natural direction for him/her.
