Lincoln’s touch-screen navigation system is bundled with Sirius satellite radio and a THX-certified audio system. It works well, even if some menus are crowded with information. Programming a destination is a snap, getting a map and zooming the screen is easy to do, setting radio stations is a breeze, and moving through the system’s various functions is almost as simple as a Lexus. A larger screen and function keys that are more spread out on the dashboard would be a big help, and a tuning knob is always on our list of nice-to-haves, but otherwise we have no complaints about the MKZ’s infotainment controls.
