I've had the new camera a week now.
The difference between the proper camera and the old crap one at night is well..... like night and day.
Even with only light from the reverse lights the image is reasonably clear and with fairly accurate colour. The old crap cam in poor light could only give light and dark only with no rendition of colour.
I think the view is slightly narrower angle than the one that I had before and the camera is mounted with the lens slightly further outwards so it is less affected by stray light from the tail lights.
t might be a little more exposed to getting rain on the lens but not a problem.
The best part is that this will end the misery of having to extract the camera from the tailgate when someone mistook it for the release button.
The view is noticeably better in the daytime too except of course when parking in front of a Nissan Micra
, but only reversing up onto the bonnet and over it would improve the view in that instance.
