Ever thought how cool it yould be to have a DVD video drive behind the 16:9 on-board-monitor ?
I can tell you: that's really cool !
... even if it was really hard work.
But: because the radio gets an error from the tape deck (sure! it doesn't exist any more) the motorized open/close function will not work any more.
I had to build a small module with a Microprocessor, listening for the iBus message when you press the open/close button to drive the motor.
(without end-position detection - just by time)
It's already some time ago I did this.
I used a generic DIN DVD Player from eBay. I had to completely reconstruct the monitor housing (e.g. lowering the screen circuit board)
Now, I would use one of mini DVD-Player.
