I am selling this after using it a few times because I installed a monitor on the ceiling of my car. The instruction manual and box are all included. There are no missing items. Slot-in 10.1 inch DVD Rear monitor car-mounted multi-player USB / SD card / HDMI input / CPRM / IR headphone compatible Rear monitor for rear seats, easy installation I believe it is in excellent condition, but please understand that it has been opened before purchasing.
