Hello i purchased my head unit dudu 7 though alibaba about a year ago and I'm having issues with the unit just shutting down and rebooting for no apparent reason, I've checked the wiring. It's fine. I did an update last week. I don't know if that might be doing it or not. I've never had any issues until today. Who do I ask for support if anybody can help me? I would appreciate it. Thank you so much
