Camera must be recalibrated when new windscreen is fitted. Just saying it should be fine is just not professional, it’s noting to do with unplugging wires it’s how the camera is mounted. The recalibration equipment used by Autoglass costs thousands and they have specially trained technicians to do this. Manufacturers clearly state recalibration is required. If the camera is out by just 1-2 degrees it can effect emergency braking and the lane departure.
But if our when you rear end someone just say rich said it should be ok. Safety first!!!
