If you're using the Carlinkit with usb-c, a usb-c to usb-c cable won't work. I don't know why. In my Skoda Scala, all inputs are usb-c. I bought an adapter from usb-c to usb-a that is working fine. I have tried a usb-c to usb-c cable to get rid of the adapter which I hoped would fix some problems, but it did not work at all. Currently, I'm back with my adapter that is working.
