If you do not have this exact part number currently in your vehicle, it will likely NOT WORK. If you are unsure of your part number, give a GM dealer a call with your VIN and they should be able to provide you with the correct part number. They may look the same and have the same plugs but data streams may be different, not allowing them to code. For example, external amps are used in some cars and will not allow interchange, etc. Operation of the iPod jack is a snap. Just plug your accessory in and you will be listening to it through all of your car speakers. Tired of listening to static over your FM modulated satellite radio? Just plug it right in and listen to satellite radio the way it is supposed to sound! Use the volume control on the radio as you usually would. It is the same with the bass, treble, fader, and balance. There is no compromise on the audio going into the jack as it is running straight into the amp.
