Thanks @bugg it's not that I am "picking nits" but due to the incident I mentioned before which all he had to do was remove 1 fuse to stop it working then if it is that easy to do then it just seems a whole load of work for nothing, so I do hope this is not the case with this system. Now
@Drago it would except the street they live on you either have to drive in and back out or vise versa lol so it did seem to go off quite a lot whilst they reversed back past other
vehicle@s ! so may be it was just set incorrectly or what I don't know.
