Yes, on the rear camera view a settings button appears. There you can choose between no lines, two lines to project vehicle position, or one line to project hook position. I have not tried with the trailer yet.When reading the text, it seems this feature has been made configurable in the camera settings.
Curious to see how that works and if I can properly judge the hook to be exactly under the hitch. I want to be able to drop the trailer straight on the hook. No pushing and pulling that four wheel trailer in a field. Too old for that.
