There are three screens for watching films or TV shows in the 450: One central multi-function screen in the front and two in the headrests for the middle seats. When watching on the nav screen, you can use the entire car and its harman/kardon LOGIC7 system as a surround-sound experience, giving you the feeling that the Tyrannosaurus Rex from Jurassic Park is actually chomping at your tailpipes. In the rear, passengers can watch in peace and quiet with their provided individual headsets that have the sound and comfort quality of Bose headphones. The SUV also comes equipped with a six-disc changer, so you'll never run out of options.
