This is your Navigation System’s control panel. Your Navigation system starts when the ignition is in the ACC or ON position. Vehicle functions are viewed on a series of screens. Use the control buttons to display the corresponding menus. There are two ways to select keys: One, touch the item on the screen. Or, two, turn the scroll knob left or right to highlight the preferred item and press the scroll knob to select. At any point you can return to the previous screen by selecting the BACK button.
