That sounds like increased manufacturing complexity and less of an ability to replace the screen with minimal labor.
Really?
Just to have a raised section (or contours) in the dash just behind the screen so at least it looks like the screen is a part of it rather than a single piece of wooden trim stretching from one end to the other as if they did not know there was going to be a screen when the dash trim was designed.
I am talking about keeping the screen floating as-is and changing the dash profile a bit - cannot imagine that makes the manufacturing complex and hard to replace screen?
