Yes its not cheap to do with the VIM and auto switch and the camera is the least expensive bit of the whole kit but its well worth while.
The auto switch means its just set and forget and no mucking around pressing buttons etc to get it up on screen when you back up.
Easy to put in, just takes a bit of time getting all the trim off to get at the wiring.
Don't forget to enable rear aux in the head unit or it won't work. I also set the camera up under the lip above the number plate in the middle and set so I can just see the tow bar. This gives me reference points and allows real accurate positioning of the car unassisted.
At home I back around a corner into some pretty tight spaces and often have to look out for kids or toys that I can't see from the road.
It also makes backing onto a trailer drawbar an absolute breeze.
Personally I think this little mod is essential in car with such a big rear end blind spot on it.
