We have now fitted a reversing camera that works with the factory head unit, no need for a 2nd screen on the dash.
This is not a how-to video!
You can get the camera we used from this link https://www.in-car-install.co.uk/shop… make sure you check your head unit before ordering.
If you want your own Roamer battery to extend your off-grid time, use this link https://roamerbatteries.com/?aff=13 Thanks to DV for helping take the dash apart 🙂
