To connect and control the iPod, connect one end of the special iPod connection cable to the iPod's dock connector. Connect the other end to both the USB port and the auxiliary input jack. The USB port and the auxiliary input jack are located in the center console bin. If the vehicle is on and the USB connection works, a GM logo may appear on the iPod. The iPod's music information will be shown on the radio's display and the music begins playing through the vehicles audio system. A standard iPod USB cable, like the one that came with the iPod, cannot be used to connect an iPod to the vehicle. You must use the special iPod connection cable that came equipped with the vehicle or that was made available from your dealer/retailer in order for this feature to work. Use the radio Menu/Select knob to bring up the iPod Menu and select Songs, Artists, Albums, Playlists and Audio books to play from the iPod. The iPod's battery charges while it is connected to the vehicle and if the ignition is turned to ACC/ACCESSORY or ON/RUN. It can also be left connected to the vehicle after the vehicle is turned off. With the vehicle turned off, the iPod will automatically be powered off and will not charge or draw power from the vehicle's battery. If you have an older iPod model that is not supported or do not have the special iPod connection cable, you can still listen to the iPod in the vehicle by connecting it to the Auxiliary Input Jack using a standard 3.5 mm (1/8 inch) stereo cable. Command and control of the iPod via the radio buttons and knobs will not be supported when only using the Auxiliary Input Jack. See "Using the Auxiliary Input Jack" earlier for more information. Press the AM/FM, XM or HDD buttons to listen to one of these sources while an iPod is connected. If a disc is inserted, press the CD/AUX button to listen to a CD or DVD-A disc. Press the CD/AUX button again to start playing and controlling the connected iPod. To properly dismount the iPod USB device before disconnecting from the vehicle, press the button directly under the EJECT label found on the iPod playback screen. 3-103
