Need some OEM rear entertainment help, 07 ML320
The DVD player only plays 1 out of 10 discs and the others show a disc error.
Dealer says its broke and wants $2800 for a new player alone

I tried cleaning, removing the unit it and really cleaning but no luck.
Went to a stereo store but they said they could not connect an after market player do to the MB proprietary plus etc.
All thoughts are welcome
