AVC-LAN CIRCUIT (MULTI-DISPLA Y CONTROLLER SUB-ASSY -
RADIO RECEIVER ASSY
CIRCUIT DESCRIPTION
Each unit of the navigation system connected to AVC-LAN (communication bus) communicates by transfer-
ring the signals from each switch.
When +B short and GND short occur in this AVC-LAN, navigation system will not function normally as com-
munication is discontinued.
In AVC-LAN, multi-display becomes the communication master, and the radio receiver assy has enough
resistance necessary for transmitting the communication.
