Title: NAVIGATION DEVICE
Abstract:
A navigation device provided with a control circuit (1) which prohibits the display of an AV system image on a front display unit (61) and allows the output of an AV system sound from a speaker (7) if it is determined that the navigation device is moving when the system is switched to an AV mode, thereby making it possible to listen into an AV system sound only as with a car radio with an AV system image display not available in a navigation device which does not permit the display of an AV system image during driving for a traffic safety reason.
