Hi,
Just saw that you have a 10.25 android screen on your GLC.
What year is your car? NTG5?
You did your instalation with the USB adapter?
Everything ok with sound??
SO many questions because i´ve installed one in my 2018 GLC, NTG 5*2 (from carlife-mall) and im having tons of problems with sound!!
The USB adapter didnt worked at all. With the BT adapter, im getting diffrente sound from right and left speakers... They are trying to help, mas its very strange....
Thanks
