I bought a jeep Grand Cherokee in 2018 with integrated DVD player.  The Car was sold long ago and I found the remote and  a head phone in my office, those were never used.
If you have a Grand Cherokee with the DVD ( It might have been blue ray player, cannot really recall it now!) this can be very handy for you a replacement or spare .

OEM item came with the car.  Never used but 5 years old, no warrnty.
