Having a TV in the car used to be a luxury. Nowadays they are much more common, especially with families that depend on them to keep kids from fighting in the back seat. If your car didn't come with a pre-installed TV, you can install one yourself with ease.
Bring the TV to the car carefully. Make sure you open a car door that will allow the TV to fit through.

Arrange the TV in the exact position you want in the car.
Plug the TV into the AC/car adapter or dual power inverter for the car and AC electronics.

Turn on the car. This will allow power to flow through the AC/car adapter or dual power inverter into the TV. You can watch the TV as long as the car is on.
