System Description: Overview: Notes

The audio unit or audio-navigation unit acts as the processor for all audio functions. Select audio functions from the audio unit or audio-navigation unit, the audio remote switch (on the steering wheel), or by using the navigation voice control system (with navigation). 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 screen (see the owner's manual and the navigation manual for more details.).

The audio system is equipped with an auxiliary input jack (AUX) in the audio unit (without navigation), or in the dashboard center lower cover (with navigation). The system accepts auxiliary audio inputs using a 3.5 mm stereo miniplug.

The audio unit or audio-navigation 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 the 12 volt battery is disconnected.

For vehicles with navigation, pressing the open/close button on the navigation display allows access to the CD slot, the 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.
