After a bit of a delay (The transport company forgot to deliver my Cactus from Sheerness) I am hopefully getting it next Wednesday. I wonder if anyone can give me an incite into the reversing camera. I'm sure once I get the car and study the owner manual, all will become clear, but first hand experience is better in my opinion. So, when you look at the screen, there is a red line from left to right, which I assume means that's as far as you should go. Two blue parallel lines, presumably showing car width, or area to keep inside of. Then two additional lines which cross each other. What are they for? And do I have the others correct?
