Indeed it is. It is wireless - so there's no wire between the control unit in the boot and the display, although I got mine many years ago, it is essentially this.

I have hard-wired the display to an ignition switched feed, and run the cable up the driver's side A pillar.

The control unit is powered from the reversing light wiring in the boot.

It works well - it seems accurate, and I know that when backing up to my garage, 1.0 will still allow me to open the garage door, but 0.9 is too close, and it hits the underneath of the LEGNUM lettering on the tailgate
