hello everyone
I recently installed the 10.25 screen on my glass 200 2016
I have 2 main problems:
1. the knob command won't work. one time it has led one time it hasn't which means it doesn't work as you can see in the pictures. I believe it is a setting problem.
2. I hear music from the OEM speakers of my car but when I get phone calls I hear it from the android speaker that I got from buying the 10.25 screen which is cheap and I can't hear nothing. how can I bypass it? I want to hear phone calls from the OEM speakers.
