Hey Jimmy, that's great to hear about your system working! I didn't find any settings using google translate (other that the DUAL, or in my case Front Screen Independent) in my van, nor my friends. I also tried to leave the battery disconnected overnight without any success. I'll try to pull the head unit and see if that works. of note; I do have the rear headrest screens that are somehow connected to the system so that may be playing a role. I doubt it though because the picture is coming through fine on the front screen.
