Speed-Sensitive Volume Compensation (SVC)

All audio systems are 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 interior noise that occurs at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four settings: SVC OFF, SVC LOW, SVC MID, and SVC HIGH that can be adjusted using the audio-navigation unit or audio unit. The factory default setting is SVC MID.
