second usb will not work on JY-UO135N4GS
i can charge my phone (Android) only so i know it has power but when i switch to any other mode usb mode will not connect to head unit. i even tried the Easy connect software that came with the head unit ... it tells me i have illegal software and to contact my supplier
what am i missing ?
The same here.
Newest OS Software is installed.
When starting Easy Connection , it says something like " Not registered. please contact Customer service"
What do i have to do?
