I’m a new user to Kurviger and not used to Apple CarPlay either, so bear with me 
Not sure if the following is possible or if the ACP actually avoid such behaviour but what I would like is to have easy access to zoom out/in. Driving a Mazda MX5 on narrow roads and trying to see how the road is bending and curving ahead, is nice. Being able to do so quickly without taking to much focus away from the road, the function should be always selected in some way to the controlling knob (centre console). Now I must navigate each time to the actual function, then zoom and after a short while this function is automatically disabled going back to some default mode. The onboard navigation actually work better, when placed in full-screen-mode, the knob always behave as zoom out/in. Is it possible to achieve the same behaviour in ACP and Kurviger?
Hello Peres and welcome to the forum!
Unfortunately neither Carplay nor Android Auto support a direct zoom function using rotary controls. Unless something changes in their policy or user interface it is not possible to offer such a function.
