The size of the screen is the same as the '17. The infotainment system itself is all new and much improved from my limited time playing with it. Here is the deal on the interior. Ram set the bar higher on the highest trim levels. On it's own the GM interior are very ergonomic, well thought and as a result very functional. What it is not, is blingy and GM is getting beat up for it. I confess I spend a lot of time in my truck and I want it nice and I want a certain level of Bling. I would be good with what is offered, but if they are going to improve it (which is subjective) I am for that. All that said sitting in the interior of an LBZ or HC level Chevy is not an uncomfortable experience and I have not seen anything written that says it is. It all depends on what you put value in. The interior is 3rd on my list, behind performance and dependability. If you think the GM interior is bad on first impression, spend some time in it and see what you think. I am not sure how anyone could step out of one and say that it isn't comfortable and functional.
