Bought a 5100. Was very excited before install. Alpine W910 just dead. Very impress with its screen. Much nicer than Alpine. But that's it. Navigation not working said hardware issue. Need to send back to pioneer. Not acceptable as a new unit. CarPlay not full function. Siri not functioning. No response from pioneer mic. I have a question. I found out the screen is laggy when showing back up camera. Day or night time. It was very laggy when see my car moving. It never happen in my Alpine or Factory unit. Does anyone have this issue? I am thinking return for refund or send back to pioneer to fix it under warranty. Back up camera is factory install and never have issue with other unit. Or this another issue with my 5100?

Exchange to another 5100, will see..
