Mercedes E220 Comand Controller not working
I am seeking help with my car's issue. I own a Mercedes E220 W212 from 2014 and my comand central controller isn't working at all.
This is the case since I installed this aftermarket android 10" screen:
The screen works perfectly, there's no issue about that. But since I installed it the comand controller doesn't work at all.
If anybody has experienced such an issue please help.
Thanks for reading.
