On our 2010, the Sat Tuner is located under the Driver's seat. There are two small metal boxes under there with wiring harnesses going into both. I believe that one is a satellite tuner and the other is for the USB/iPod integration. I'm not certain that this is true for the 2011, but that's where I'd check first.
