Audio System

When using the in-vehicle Bluetooth system, sound comes through the vehicle’s front audio system speakers and overrides the audio system. Use the audio system volume knob, during a call, to change the volume level.

The adjusted volume level remains in memory for later calls. To prevent missed calls, a minimum volume level is used if the volume is turned down too low.
