I was looking on the Honda web page and found a listing for the backup sensors that are factory. It is an option that must be dealer installed. I found 4 dealers in Southern California listed as Clarity service specialists. The page says the unit plus the 2 hours time to install is around $450. Has anyone had the the Honda system installed? does it interface with the display or is it a separate set of lights and warning noise. I am looking at it and am only interested if it displays as an original piece of equipment.
