PROBLEM TO BE SOLVED: To provide an audio navigation system capable of continuing the route guidance as far as possible while protecting the system at the time of high atmospheric temperature. SOLUTION: The audio navigation system (1) comprises: a temperature detection means (temperature sensor 8) for detecting the temperature of a navigation device (2) and an audio device (3); and a controller (7) for controlling a plurality of functions of the audio navigation system (1) successively corresponding to the rising of temperature data detected by the temperature detection means (temperature sensor 8). The controller (7) stops first the functions other than the route guidance function from among the plurality of functions of the audio navigation system (1) when the navigation device (2) is during route guiding.
