To provide a navigation device capable of performing screen switching or superimposed display at a convenient timing respectively to a driver or an occupant seeing/hearing a digital broadcasting.

This navigation device is equipped with a control part for generating a control timing for showing whether a prescribed broadcasting is being received, based on an analysis result, or the like, acquired by analyzing detection information or a plurality of received signals detected from the digital broadcasting received by a broadcasting receiving part. For example, a timing signal for showing that a CM, or the like, which is not related directly to a program main part is being received is generated from management information, or the like, included in digital broadcasting waves, and a display content is changed by using the timing shown by the signal. As a result, a route guide image that excludes a map image, for example, an arrow showing right/left turns, a character image, or the like, is displayed on a display part. In this case, a digital broadcasting reception image and a route guide image are displayed in a superimposed manner on one display part.
