I have a 2011 LR2 with problem while towing in reverse where the parking sensor is on constantly when (in reverse), due to it sensing an object in back of the truck (my trailer!). I am told there is either an interrupt switch for "situational disabling", or alternatively, the volume button on the radio is supposed to mute the beeping. Can't find the disabling switch and the volume control does not work. Any ideas? Land Rover installed an aftermarket wiring harness that does not interface with the Parking Aid. I like the Parking Aid so I don't want to permanently disable it...just when backing up the trailer.
