ABSTRACT:
A display unit for presenting messages from a motor vehicle in which messages are selected for presentation based upon the number of interruptions in the power supplied to the display unit. A power supply provides power to an interrupter, which produces, within a first predetermined time frame, interruptions in the power. The power interruptions are sensed and counted, and a timer measures the first predetermined time frame in which the interruptions in the power occur. A message storage means is provided, in which is stored at least one message to be presented. A controller selects one of the stored messages for presentation, based on the number of interruptions sensed in the power and the first predetermined time frame during which the interruptions occurred, and the message is presented on a display panel. In a preferred embodiment the controller ceases the presentation of the message after a second predetermined time frame, which is most preferably about three seconds.
