I looked, and looked, and keep looking.
I need to replace one OEM monitor.
Any help? It can OEM or any other major brand.
MB dealer wants $2,000 to replace it, and I found several places where they offer two monitors for $600-700 on brands like Alpine or Sony.
Any ideas? Any DIY write up?
For $2,000 I can get me a new big screen plasma and Blue Ray player.

For that price you can install after market headrests with new screens and the players are built into the headrests so that both screens play different movies and sources. Dump the factory screens and go after market they will be better.

The dealer told me that it will deactivate the head restraint system for both headrests. Once again the dealer told me.

Once again, don't believe everything the dealer tells you

The same dealer will very happily install an aftermarket RSE in your car and will swear that it will not impact the Active Head Restraint.

Beto--I just spoke with a guy in the parts department, and for some reason what your dealership was telling you is not incorrect. He said that for ONE replacement unit, if you have memory seats, is $2000+...seems ridiculous

I took the car to the dealer, and it seems that the screen was impacted by something (kids playing in the back) and they can't replace it under warranty.

Yeah, I know it's crazy, even the lady from the parts department raised her eyebrows when she saw the price.
I don't understand Mercedes, like they don't want to sell you a replacement screen.
I even contacted the supplier, Delphi/Grundig, in Germany and they don't want to sell me a single screen.
Does anybody know how to remove the screens? I'm sure I can fit a universal 7" screen or two if I can remove the OEM's.
Otherwise, I'll get the Vizualogic or similar equipment.

At this point, I would say check with an aftermarket shop in your area. They may have some options for you. All the best.
