B-B-B-But the '21s have the temperature displayed on the knobs ALL THE TIME. Anything less is unacceptable.Wait so Apple CarPlay only lets you see the temperature for a split second? I use Android Auto and its up for at least 2 seconds. Granted short, but if I am driving I shouldnt be paying attention to the AC temp setting and just cranking the power dial from low and higher. And that still stays on the screen for at least 2 seconds.
