Giant side mirrors, thin windshield pillars given the Navigator's size, and third-row headrests that collapse forward for an improved view through the rear glass all contribute to good outward visibility. It helps that the Navigator towers above surrounding traffic. Reversing takes planning, especially with the third-row seatbacks blocking the lower third of the back glass, but with rear parking sensors and a tight turning circle for such a big SUV, it's better than some. Still, we wish a reversing camera was offered on the Navigator.
