Just curious if anyone else has run into this problem, still running the oem head unit so it may be fixed once i swap the touch screen in, but currently when I connect my phone I need to unplug and plug back in the usb for it to register/connect? I've tried different cables ect always the same problem. But I only have this issue maybe 75% of the time when connecting the phone. any ideas or is this normal? cars literally 2 weeks old less than 500km on it still.
