The center of attraction is the iCN 750's 4-inch diagonal touch screen. It boasts 480-by-272-pixel resolution, so text and map images are vibrant and sharp. The touch screen is responsive, but we had some difficulties viewing the screen in bright sunlight and noticed it had a tendency to collect a lot of smudges. Luckily, Navman includes a screen shammy as part of the package. To the right of the screen are five shortcut keys: gas (displays gas stations nearest your current location), parking (highlights nearest parking garages), main menu page, go-to menu page, and a button that cycles through the 3D map, 2D map, next turn, and turn-list screens.
