Has anyone had a reversing camera fitted?

I'd also like to know..

You can get universal ones but is it really needed on such a small car?

IMHO a reversing camera is a bit pointless on a car with no built in media/sat nav screen.

 

'Er indoors has both parking sensors and a reversing camera on her car. The camera is useful but the parking sensors are even more so. I would forego the camera and stick with parking sensors if I had to choose one or the other.
