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 ECM/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 (Music/Speaker) button repeatedly until the SVC is displayed, and rotate the VOL/SELECT knob 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 (SVC OFF, LOW, MID, or HIGH).
