With the exception of the screen size I can do all of that with my phone in a mount as well. But you shouldn’t be operating your phone while driving, not even with CarPlay. It’s illegal in many countries.
Your phone in a mount provides integration with your car's steering wheel buttons to allow for control without taking your hands off the wheel? Your mount allows you to leave the screen on your phone off while also using navigation with a screen?
Exactly. You shouldn't be touching screens with your hands while you drive. That's illegal where I live. But my dash mounted phone has Siri and Bluetooth so I can be hands-free for commands and I can use the steering wheel controls for media.
I don't know that I believe that.
