What does the AUX adapter help?

The AUX adapter can be terminated with a 3.5 JACK connector or 2x RCA connectors. It can be plugged into the place of the CD changer, or into an already designated position, on the back of the car radio . In some cases, you need to enable this function for diagnostics. An external audio source - MP3 player, tablet or smartphone - can be connected to the factory car radio using the AUX adapter.
