AVC-LAN Plus Circuit |
DESCRIPTION
The navigation system uses AVC-LAN plus communication between components when performing sound library recording, and when displaying the satellite radio traffic information screen.
If a +B short, ground short, or other malfunction occurs in the AVC-LAN plus circuit, communication is stopped and the system does not operate normally.
