Does this work on a car without a factory screen?

Yes. The kit is built for vehicles that lack a factory infotainment display, using its own screen instead of the car's.

Can I use it on a truck or trailer?

It suits trucks and trailers where rear visibility is poor. Check that the camera mounting and cable length reach your setup.

Guidelines depend on the camera unit in the kit. They are not tied to the vehicle's steering angle the way factory systems are.

The camera mounts at the rear and a cable runs to the display in the cabin. Expect to route wiring and tap a reverse light or power source.

This is a backup camera kit for live viewing while reversing, not a dash cam. It does not record footage.
