Hi, I bought this radio:
https://es.aliexpress.com/store/pro...lgo_pvid=a1a482e1-a264-4e17-9ae3-6338fadf4832

Octa Core, 2 Gb Ram, 32 Gb Rom, 7 inch, Android 7.1.2.

I have found all the Passwords:

Extra Settings : 123456
Developer Options: 7890
USB Debugging: john@tw-desktop

But I can not root the radio, I tried Kingoroot, Kingroot and One Click root without success, could someone help me?
I have another problem, steering weel control its 3.3v and my car woks whith 4.2v and no Can Bus.
Thanks.

See this thread on how to root (pages 28 and onwards). You have to flash a new version of the firmware that has had root access added.
