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.
