Hi Mate @dinesh
Thanks for the good word.
Sorry I can not help you because I completely do not know the devices 2DIN.
Hint was that on our forum this topic had already been moved - so use search option and search for posts 2_DIN type, volume, etc. 2_DIN
You should find it.
If not - go to the section Discussion and place a new Post - question, like I have such and such a problem - how to solve it?
PS do not know if it helps, but I've seen sys.txt files with records - navigation_audio_stream = 0 (6) - try.
