Got a vehicle in your shop because the navigation system display screen won’t automatically switch to Night mode when you turn on the headlights? The reason could be the dash illumination control setting. NOTE: Depending on the vehicle that you’re working on, this control could be a knob, a button, or a pair of buttons. If the control is set to full brightness when the headlights are on, it overrides automatic display mode switching and the display screen stays in Day mode no matter if the headlights are on or off. This comes in handy if you’re driving in daylight with the headlights on but you want the display screen bright so that it’s easier to read. To fix this problem, here’s what you need to do: 1. Start the engine.

2. Turn on the headlights, and adjust the dash illumination control setting from full brightness down a few clicks to middle brightness. 3. Turn off the headlights, and shut off the engine. 4. Start the engine again. 5. Cover the sunlight sensor on the dashboard with a towel to keep any light from reaching it. 6. Turn on the headlights, and watch the display screen. • If the display screen switches to Night mode, you’re done with this repair. Remove the towel from the sunlight sensor. • If the display screen stays in Day mode, refer to the Navigation System section of the applicable S/M and continue with normal troubleshooting. For more info on automatic display mode switching and for recommended display mode settings, check out System Set-up in the applicable O/M.
