If that's not enough to satisfy your inner audiophile, the optional Alpine Premium stereo adds a different faceplate with a touchscreen interface and a knob that combine to mimic an iPod's controls. A series of buttons makes switching among the seven different audio sources easy. Also included with the Alpine system is HD radio, a "media expander" that improves the sound quality of digital music files and additional RCA outputs for further expandability. A navigation system and a back-up camera can also be added to the upgraded stereo.
