Anyone tried anything like this?
I was wondering if it could be setup to use the existing backup camera feed?

 

I looked into this before, but not sure if it can use the existing backup camera feed. You might need their cameras to calibrate the system. Some reviews said the backup camera was same size as the stock one. It might also be a wider angle camera.
Someone should take on this mod

 

This guy did the install with a similar system on his Lexus GS:
