Vehicles with Navigation System
The rear vision camera system is designed to help the driver when backing up by displaying a view of the area behind the vehicle.
When the driver shifts the vehicle into R (Reverse), the video image automatically appears on the navigation screen. Once the driver shifts out of R (Reverse), the navigation screen will go back to the last screen that had been displayed, after a delay.
