So I bought a cheap (£108 Amazon) stereo to replace the even cheaper temperamental Double din stereo.
I couldn't resist fitting the Free reverse camera
I didn't want to screw it into the rear bumper, so got a bit creative.
Had to run a live feed off the rear wiper plug (JDM Yo).....lets me select it while not in reverse. And then connected the stereo 'Reverse' signal wire to the fuse box (reverse light power). So comes on automatically when sleeting reverse.
