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. A still
further advantage is realized by providing a technician servicing the
vehicle with a microphone operative to interrupt the audio signal of the
presentation so as to convey vehicle service information regardless of
whether the presentation is viewed within the vehicle compartment or in a
remote waiting room. The audio-visual presentation is readily tailored to
the past viewing and/or purchase history of a potential customer.
