I recently purchased a 2017 Lexus LX 570 that a non Lexus dealership replaced the backup camera. The camera is the correct part number from Lexus. The image on it is mirrored and there are no gridlines. When I go to the service menu for camera settings, the menu options are grayed out and I cannot get into them. The only option I can get into is the vehicle color. Does anyone have any idea how to fix this?
