Friend of mine has an '04 F250 that he plows with. Is there a way to de-activate the sensors in the rear bumper so the "alarm" quits going off? He asked the dealer and pretty much got the run around... how it's unsafe to use the vehicle without it and the liablities were too great for them to even think of assisting him. You can shut this system off by hitting a button, but he says everytime you put it in reverse, it resets itself and you have to push the button again. Sorry for playing middle-man here, but I told him I'd post this and see if anyone knows of a "fix". Thanks.
