In order to prevent this, a flag is provided in the received data storage buffer to distinguish between the initial congestion data and the second and subsequent congestion data, and a timer is provided to distinguish between instantaneous congestion and continuous congestion. A device for preventing erroneous display, characterized in that it is provided with means for displaying a traffic jam only when the traffic jam continues for a certain period of time.
