Overview
The audio-navigation unit or audio unit acts as the processor for all audio functions.
To select audio functions, use one of the following inputs
- Audio unit or audio-navigation unit
- Audio remote switch on the steering wheel
- 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 system information for more details.).
The audio system is equipped with the auxiliary input jack (AUX) in the center panel (Except DX model without navigation), or in the center lower trim (with navigation and DX model without 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 the 12 volt battery is disconnected.
A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle's security system.
Speed-Sensitive Volume Compensation (SVC)
The audio system is equipped with speed-sensitive volume compensation (SVC). The audio-navigation unit or audio unit receives the vehicle speed pulse (VSP) from the PCM. The system processes the speed input and increases the navigation or audio system volume level as the vehicle speed increases to compensate for the various interior noises that occur at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four settings: SVC OFF, LOW, MID and HIGH that can be adjusted using the audio-navigation unit or audio unit. The SVC comes from the factory with the MID setting as the default.
To change the audio unit SVC setting, press the sound (J>/2]) button (Except DX model) or the TUNE/SOUND knob (DX model) repeatedly until the SVC is displayed, rotate the VOL/SELECT knob (Except DX model) or the TUNE/SOUND knob (DX model) to adjust the SVC to the desired setting (SVC OFF, LOW, MID, or HIGH).
To change the audio-navigation unit SVC setting, press the AUDIO button, and then select the SOUND icon on the navigation display. Press the navigation display to select the desired setting (OFF, LOW, MID, or HI).
iPod Operation with Audio Unit
When an iPod is connected to the audio unit with the USB port, you can navigate through the iPod's music files with the VOL/SELECT knob and the l<< >>l button on the audio unit. You cannot use the iPod's controls.
The AUX terminal is a sound input terminal. When you connect an iPod to the audio unit using the AUX terminal, the audio unit can not control the iPod except for the volume control. To select and play songs, use the iPod's control.
Because hardware and software continually change, make sure the iPod is compatible with the vehicle by referring to the applicable owner's manual.
