> The infotainment screen mounted in the center of the dash isn’t a touch screen; users must adjust audio and infotainment features using steering wheel controls or the rotary controller and buttons mounted between the front seats. Unfortunately, some steering wheel controls are hard to see and difficult to use because they have silver text on a silver background. The rotary knob and buttons in the center console are also challenging to use since many of the buttons are difficult to see at a glance, and the lack of an easy-to-decipher menu structure forces drivers to spend too long looking at the controls instead of the road.
As can be seen from your first link, the main control method is a jog-wheel knob at your knee next to the gear shift lever, mounted facing up, so you turn it left and right to select things and push in to "click"/confirm. CR says that with this control system, and the menu hierarchies that Mazda's UI makes you go through, you end up more distracted than with the better touch-screen systems they review.
