Auxiliary Audio Input Jack

WARNING: This page is about a different car, the 2010 Cadillac SRX. 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. The auxiliary input jack circuits may be connected directly to the radio, or to the multimedia player interface module (if equipped). When a portable audio playback device is connected to the auxiliary jack, an internal switch opens the detection signal circuit and the radio will switch to AUX as the audio source.

When not equipped with the multimedia player interface module, 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.

When equipped with the multimedia player interface module, all circuits from the auxiliary jack are connected directly to the multimedia player interface module. When a device is connected to the auxiliary jack an internal switch opens. The multimedia player interface module detects the device and sends a serial data request to radio to switch to AUX as the audio source. Audio signals from the device are sent to the multimedia player interface module from the auxiliary input jack via the left, right, and common audio signal circuits. The multimedia player interface module then outputs these signals to the radio.
