Hi , I have just found the dealer fiting instructions for front sensors and I am now completely confused as the dealer said that the display would show the distances at the front of the vehicle, this is from the fitting instructions and no mention of the visual aid on the LED screen, question points in red, the only benefit over the cheap ones is that the activation is automatic, depending on speed of if you were in reverse 20 seconds ago.
