Hi I am looking to replace my rear parking sensors for my CR-V EX. One broke (see pic attached) and is being held on by a cable tie! And now one has recently been stolen (see gaping hole left in pic!). When I reverse I now just get a continuous high pitch beep as if I am about to touch something. I called my dealer for a part number but he believes this could not be a genuine part as CR-Vs do not have sensors on the rear bumper like this. I'm at a bit of a loss as to what to do/where to find a replacement part??? Any help much appreciated please! Thanks.
