I fitted PDC to my Navara becuase I dinged the tailgate the very first day I got it, reversing into the garage I did not see my work bench chair. Bought the kit from China Mall nogal for R470 plus it has a dash display which shows you how far you are from obsticles and whether its on the left or right.
I was nervous drilling holes in the chrome bumber, but it looks profesionally fitted and it works 100%. I can even switch it off for when I tow the caravan and want to park it.
