This is true, I was refering to the factory installed units. I have not had to replace or repair any of these except for one that was damaged in shipping.
Most True "factory installed " units are very wel built pieces. the problem with them is the fact that they are usually much smaller monitors or they lack the features that most people want.That is why so many dealers go outside and get it done, becasue they can get a bigger monitor with more bells and whistles for the same price of the OEM units.
