I was given one of these years and years ago for Christmas. Fitted it to a VW Bora V6.... It was useless. Sometimes it would beep at five feet, other times at 5 inches. It didn't work in the rain and sometimes wouldn't work at all.Hugely unreliable and imprecise. Hence why OEM solutions always use ugly sensors, its the only way to make it work properly.
