I hate having to use these screens as i need a pair of reading glasses for reading but another pair for driving. Lucky my wife is usually in the car on long drives to alter heating and vents. On the last car,even trying to work the sat nav was a task from hell.
I did speak with Mercedes about some controls being difficult for the mostly elderly buyers of the new cars and they do take it on. Many alterations to make it easier in the new models so maybe a lot of people suggested improvements.
I might buy another Merc but engines are mostly 1.3 litre turbo now. The diesels worked a lot better
