GA-Net Bus Configuration: Notes
WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
The GA-Net bus passes audio, RES and navigation commands throughout the navigation, RES and audio components. These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM station and music title names. Because the entire bus is "daisy chained" between components (see diagram), any open or short in the GA-Net bus harness can cause any one or all of these functions to become inoperative. The addition of any audio accessory must maintain the continuity of the GA-Net bus by installing the "Y" cable included with the accessory kit.
