AVC-LAN Circuit Between Radio Receiver and AMP

AVC-LAN Circuit between Radio Receiver and AMP

DESCRIPTION
Each unit of the navigation system connected to the AVC-LAN (communication bus) communicates by transferring the signals from each switch.
When +B and GND shorts occur in this AVC-LAN, the navigation system will not function normally as communication is discontinued.
In the AVC-LAN, the multi-display becomes the communication master, and the radio receiver assembly has enough resistance necessary for transmitting the communication.
