Thank you. I wrote to customer services.
So you say its not possible to carry out a touch function system drivers reset?
Are you sure the problem is the screen itself and if I replace the screen the problem comes fixed?

Hope your kind understanding.

Hi. Thank you for the assitance the last time. I replaced the Touch screen and the problem is fixed but now I am having problems with the audio.
Since I reinstalled the MCU and carryed out a lot of resets in my android car stereo, I just can hear sound from the radio stations, but I can´t here sound from the any other media (for example: mp3 music, or from youtube I can see the video but I cant hear the sound of the video). The music player is working but I cant hear any sound. I think the problem is software. May be the MCU. And the other sympthom that my car stereo have is that I just cant change the color of the appearance bottoms to green color. If I want to change to another color it doesnt work. Please can you help me with this? If you need my buy information and the car stereo specifications again, you can check my previus message of this forum and there are its.
This is the MCU version I have:
