8. AVC-LAN Description
(a) What is AVC-LAN?
AVC-LAN, an abbreviation for ºAudio Visual Communication Local Area Networkº, is a united standard
developed by the manufacturers in affiliation with Toyota Motor Corporation. This standard pertains
to audio and visual signals as well as switch and communication signals.
(b) Purpose:
Recently, car audio systems have rapidly developed and the functions vastly changed. The conven-
tional car audio system is being integrated with multi-media interfaces similar to those in navigation
systems. At the same time, customers are demanding higher quality from their audio systems. This
is merely an overview of the standardization background. The specific purposes are as follows.
(1) To solve sound problems, etc. caused by using components of different manufacturers through
signal standardization.
(2) To allow each manufacturer to concentrate on developing products they do best. From this, rea-
sonably priced products can be produced.
HINT:

If a +B or GND short is detected in the AVC-LAN circuit, communication is interrupted and the audio
system will stop functioning.
