Auxiliary Audio Input Jack
WARNING: This page is about a different car, the 2016 Chevrolet Malibu Limited. However, it is still accessible from the selected car via links, so may be relevant.
The 3.5 mm (1/8 in.) auxiliary audio input jack is located in the console. All circuits from the auxiliary jack are connected directly to the radio. When a device is connected to the auxiliary jack an internal switch opens. The radio detects the device and switches to AUX as the audio source. Audio signals from the device are sent to the radio from the auxiliary input jack via the left, right and common audio signal circuits.
