Large 9-inch screens that fit all types of cars in the headrests, and all car sizes are available. A complete set with the screens. You connect it to the power port that comes with it, and it works with the remote control. You can connect speakers to the screens, or play through the car's speakers, or use the speakers built into the screen itself. The screen displays high-definition HD videos, images, or audio files by connecting a flash drive with the clips. You can play one screen or both together. Connecting it is very easy and you can do it yourself. I installed the screen on the car and it was working fine, but I sold the car and removed the screens. One of the screens has a small circle shown in the pictures, which does not affect the screen from the first time I removed it. Other than that, it works efficiently. Asking for 300 riyals for the complete set.
