I see this is option that is vary seamless for the 1998-2002 Lx470. Couple question on this unit and the monitor on the lx470. What is the resolution of the camera input to the Navkis. I see it has two camera inputs. If I use them both does it split the screen or switch them via a toggle or how? What is the resolution of the Lexus monitor? Cameras are cheap these days I want to get the best possible if it takes advantage of the quality.
