HELP! I am now in the process of preparing to button everything up, but a run through test first. In doing so, here's my problem: The Carplay is via usb to iPhone. The extending/retracting of the flip screen is normal with usb cord plugged in. When I plug the usb cord into the iPhone the screen will retract. If a hook phone up and then push button to open screen, it goes short of full open, I can see something on the screen before it starts retracting. I did notice that the HVAC back lighting bulb would glow at different levels as the flip screen was operating.
