AUX in jack
AUX-in jack is intended for connecting external audio equipment to amplify the sound. If connection is made
correctly, the audio signal from the external source will be translated through the acoustics of the head unit.
This enables to adjust the volume and quality of the sounding. For example, you can connect an MP3-player
to listen to tracks using the car acoustic system.
