The camera I bought for my vehicle was so necessary. With children running behind cars today, it is always important to make sure you are clear when backing. I bought this camera for that purpose. On my particular vehicle (2007 Mini Cooper Conv) there is not a good line of sight to the rear. One word of warning is that on this particular model of vehicle, when the camera is attached you have to flip it over as it does interrupt with the trunk mech. not allowing access to the switch. I was able to easily modify the position of the camera and flip it over to make it work. It is also better this way as well since it is on the lower part of the plate giving better visibility!
