so... I have one in my ix20, but I imagine probably the same unit in most of the other models. mine is just about viewable, it is very unclear and very little colour. I am sure that when I got the car, it was clearer. I had a look at the camera, or where I think it is, and nothing obstructing. So just wanted to check, how clear it should be.
my friend has a Mazda.. it is so clear, can see all colours, read number plates etc..
