Auxiliary Devices

Using the Auxiliary Input Jack

Radios with an auxiliary input jack located on the lower right side of the faceplate can connect to an external audio device such as an iPod®, MP3 player, or CD player, for use as another source for audio listening.

This input jack is not an audio output; do not plug headphones into the front auxiliary input jack.

Drivers are encouraged to set up any auxiliary device while the vehicle is in P (Park). See Defensive Driving on page 9‑3 for more information on driver distraction.

To use a portable audio player, connect a 3.5mm (1/8 in) cable to the radio's front auxiliary input jack.

When a device is connected, press the radio CD/AUX button to begin playing audio from the device over the vehicle speakers.

For optimal sound quality, increase the portable audio device's volume to the loudest level.

It is always best to power the portable audio device through its own battery while playing.

Connecting a USB Storage Device or iPod®

The USB port can be used to control an iPod or a USB storage device.

To connect a USB storage device, connect the device to the USB port located in the center console or on the instrument panel.

To connect an iPod, connect one end of the USB cable that came with the iPod to the iPod’s dock connector and connect the other end to the USB port located in the center console or on the instrument panel. If the vehicle is on and the USB connection works, “OK to disconnect” and a GM logo may appear on the iPod, and iPod appears on the radio display. The iPod music appears on the radio’s display and begins playing.

The iPod charges while it is connected to the vehicle if the vehicle is in the ACC/ACCESSORY or ON/RUN position. When the vehicle is turned off, the iPod automatically powers off and will not charge or draw power from the vehicle's battery.

If you have an older iPod model that is not supported, it can still be used by connecting it to the auxiliary input jack using a standard 3.5 mm (1/8 in) stereo cable. See “Using the Auxiliary Input Jack” earlier for more information.
