Overview
The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit, the audio remote (on the steering wheel), or by using the navigation voice control system. The audio display provides the current audio status. For vehicles with navigation, additional audio information is available by touching the audio button on the navigation audio screen. (See the owner's service information and the navigation system service information for more details.)
The XM receiver and audio disc changer passes its signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus. Any open connections in the GA-Net bus circuit will cause audio and navigation functions to appear inoperative.
For vehicles with navigation, pressing the open/close switch on the navigation display panel allows access to the CD slot and PC card.
A security signal is daisy-chained between the audio and vehicle components and integrated into the vehicle's security system.
iPod operation
When an iPod is connected to the audio unit with the USB adapter, you can navigate through the iPod's music files with the VOL/SELECT KNOB and the <----> key on the audio unit. You cannot use the iPod's controls.
When you connect an iPod to the audio unit with the AUX connection, you can use the iPod's controls, but not the VOL/SELECT KNOB as the AUX connection is only a sound input terminal.
Because hardware and software continually change, make sure the iPod is compatible with the vehicle by referring to the applicable owner's service information.
