Hello Friends,

i am a premium user and have a multimedia in my car (Eonon) that have android operating system. When I try to change the place where the offline music is stored, pops up a windows to confirm the location but the button "continue" or "OK" don't show. I think it's because of the screen resolution. Is there anyway to confirm?
