Yes if the NAV screen is blank and there is a 50 51 flashing in the small green LCD screen then the screen has lost communication with the module in the trunk. In some cases the module will need to be replaced but we should perform some checks first. First remove the disc to check it for damage. A new disc will load new software which may correct this. We also should check the fiber optic cable as sometimes it comes loose located under the driver side dash. It is the black and white connector with two black cables. We also can try un plugging the NAV module to see if it will reset.
