Description
- Compatibility: While advertised as universal, the headrest posts need to be adjustable to fit the width between the posts on your headrests. Double-check the minimum and maximum post width adjustment range of the headrest monitors you are considering.
- Video source: These monitors typically don't have built-in DVD players, so you'll need a separate video source, such as a portable DVD player, a game console, or a connection to your car's entertainment system. Make sure your car's entertainment system has video outputs compatible with the headrest monitors (usually RCA composite or HDMI).
- Power source: The headrest monitors will likely need to be plugged into a 12V power outlet in your car.
- Audio: Some headrest monitors have built-in speakers, while others rely on headphones (wired or wireless) for sound. Consider how the passengers in the back seat will listen to the audio.
