Have my new GX460 for a short while. For the most part I am pleased, but one of my largest frustrations is lack of any reference markers when the vehicle in is in reverse. My 2006 QX56 had reference lines that showed the track of the SUV. The BMWs and others even have tracking lines that adjust based on the current steering position. I get a clear picture with the camera, but without reference marks it is hard to backup with confidence. Our house has a tight turnaround area, so this is a real need of mine. Any help or suggestions greatly appreciated!!
