Familiarity is breeding approval of Lincoln’s DVD navigation system. With Sirius satellite radio and THX-II sound, the audio system itself sounds great. Lots of bass, good high end, and an overall good listening experience. We’re not audiophiles by any stretch, but all agreed that it sounded excellent, and major controls are duplicated on the steering wheel. We do wish that the buttons were a little bigger, but it’s a minor complaint. The navigation system is simple to use, with an intuitive touch-screen interface that is quick to program.
