The nav-u is a portable navigation system with a 3.5/4.3-inch screen in a thin, compact housing. The display is surrounded by a metallic-color frame to show toughness and attention to detail, and emphasizes thinness. A flip antenna is placed in the center of the back of the body, moving the antenna out of view where it cannot obstruct the field of view. In addition, the GPS antenna and compact cradle are formed as a single piece, for simple attachment and a smoother look.
