A backing system for a vehicle and trailer includes a wireless control device in communication with an electronic control unit. The electronic control unit is configured with programming to record an image of a hitch for the vehicle and trailer assembly and determine a hitch angle using a plurality of reference points on the trailer which are viewed by the camera. The portions of the image which are relevant to a current position of the vehicle and trailer assembly are determined by the electronic control unit. Data regarding the relevant portions are sent to the control device via a secured wireless connection and displayed on a display.
