It's truly awful. The last time I bought a car I wanted to take a hammer and smash the freaking "screen" because the UI was such a POS (VW Beetle). A 20-year-old radio is a better audio system, and the cheapest smartphone is a better navigation system than anything that comes in a car nowadays. But I suppose the manufacturers think they can't sell a car nowadays without "teh shiny screen." And they might be right.
