I'm sure if you went to a local auto electrician, he could wire a relay to stop the power to the sensor unit when you engage reverse.
My kit cost £14. Fitted to my daughter's car last year as a guinee pig and found them to be reliable. If you fit them yourself, when fitting the sensor DONT push the centre section in, push them in by the outer ring.
