Abstract: An audio-visual presentation system delivering a presentation to a vehicle passenger compartment is provided that includes a video display mounted external to a vehicle passenger compartment and viewable from within the compartment. A controller provides a video signal to the display and an audio signal. The audio signal is broadcast by an antenna coupled to the controller as a radio frequency is received by a vehicle radio and discernable to a vehicle sound system. The audio-visual presentation system is particularly well suited as a method of education and sale regarding vehicle service products. Rather than providing a discernable audio signal through a vehicle sound system, it is appreciated that a portable radio set is readily placed within a vehicle passenger compartment or the audio signal delivered via a wireless network.
