GA-Net Bus Configuration

The GA-Net bus passes accessory and USB commands to the navigation unit.

Because the entire bus is daisy-chained between components (see diagram), 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. If the accessory comes with a Y cable, make sure it is installed.
