GA-Net Bus Configuration
WARNING: This page is about a different variant/trim than selected.
The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include audio/XM selections by voice, and XM station and music title names. Because the entire bus is daisy chained between components (see diagram below), any open or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition of any factory audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with the accessory kit.
