I bought the unit on this web site, got a local guy to install both for $105. He put antenna above front windshield on drivers side and mounted XM unit under passenger side floor mat (against the wall). The Prius shop XM is the real deal, I would recommend anyone buy it. It took 2.5 hours but guy had never installed anything on a Prius. His shop is located in Vanita OK. which is northeast of Tulsa.
