Touch assistance turn OFF ?

I got a couple of questions for my Joying in my Volkswagen Sharan.

1.) How can I disable the assistive touch point on the display?

2.) Is there a way that the Head Unit will automatically initiate the Apple CarPlay when I start the engine?

3.) I use my iPhone as a hotspot for the Joying. Is it also possible to link into the hotspot if my mobile phone when I start the car?

Sorry for so many questions, but the menu of that device is really packed and I didn’t get a clue where to enable or disable all these little things.

Thanks and many greetings!
