No one makes a DIN or other dash format with BluRAY. Those Crutchfield gizmos in the link posted are all BluTOOTH. Been there done that and here's what we had to do to solve: Went on Ebay and bought a used sony blue ray player and velcro'd it to the shelf under our TV. It's been a few years, but I think we paid around 35 bucks and still works fine. Once upon a time there were three brands of TV's that had a blue ray slot in the side of the frame, but they got pulled from the market years ago for some reason. Here's the correct Crutchfield link for blu ray players and you'll notice they are all 'family room' format....ie big.
