The first seamless integration of iPod and automobile. Connect with your music like never before. With the installation of an integrated adapter developed by BMW and Apple -- now available for the BMW 3 Series, X3 and Z4 -- you can control your iPod through the existing audio system and multi-function steering wheel. Which means no loss of power. No loss of sound quality. And no loss of control.
