Has anybody done this on a VRS Hatch. I thought it would be easy stick holder just under brake light on heated screen wire into power feed to rear brake light with inline fuse. I have read on various sights this is a no no as the camera would suffer shock and vibration caused by opening and shutting the boot. Your thoughts please. My only worries are that and sticking the holder on a heated rear screen.

This is one my to do list too. When I last looked into doing this IIRC Boss Fox recommended fitting it to the rear screen, running the wires down the inside of the hatch .and picking up the live feed to the rear wiper inside the hatch
