ABSTRACT:
A car navigation system comprises a sound output means for selectively changing the voice sent to a speaker between male voice and female voice in accordance with the advancing direction of the vehicle. In addition, using a plurality of speakers, the voice guidance is given from a direction identical with the advancing direction of the vehicle. Furthermore, stereo sound generated from the speakers can be selectively attenuated in accordance with the advancing direction of the vehicle, so that the driver of a vehicle can intuitionally perceive or grasp the correct advancing direction of his/her driving vehicle, while listening stereo sounds.
