Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Description: Overview: Notes
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 manual and the navigation system manual for more details).
The audio system is equipped with the auxiliary input jack (AUX) in the center panel (without navigation), or in the center lower trim (with navigation). The system accepts auxiliary audio inputs using a 3.5 mm stereo miniplug.
The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when battery is disconnected.
For vehicles with navigation, pressing the open/close button on the navigation display panel allows access to the CD slot, a PC card slot, and the navigation DVD.
A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle's security system.
