Please provide installation instructions
The first step is to find a channel to open the background access permission of the infotainment system. The permission control of the 26 models is relatively strict.
The 24 models can directly access the background using apps like Gaode Maps, QQ Music, etc.
I just can’t find a way to access the backend permissions 
It was possible to find a channel to pay for opening it a while back, but recently the official authorities have been cracking down, so I guess it’s not possible to open it anymore.
What version is it now?
