The Cobra 8500 HD truck GPS is a touch screen unit designed with professional drivers in mind. Physically the unit looks and feels nice. It comes in at just under 1 inch thick, 7.2 inches wide, and 4.6 inches tall. The 7 inch high-definition display occupies most of the territory with only a small black bezel around the edge. Weighing in at 10.4 ounces it is lighter than comparable models, which is nice when using the included windshield mount.
