Abstract
A voice guidance switching device for use in a car navigation device. When a navigation control section receives a signal from one of a controller and a controller, the navigation control section determines whether the signal is a first signal or a second signal. When the signal is determined to be the first signal, the navigation control section reads a voice guidance switching program from a storage medium and determines whether the signal has been transmitted from the controller or from the controller. The navigation control section also determines whether or not the vehicle is travelling at the time on the basis of a signal from a speed sensor, and then switches a voice guidance generating program between an operable state and an inoperable state on the basis of these determination results.
