I've replaced the HMI ...no change.
I've replaced the USB cable because some people said their dealer did that to fix their issue. No change.
I took the display apart and removed and re-seated the flex cables that connect the circuit board to the display. No change
The next step is getting a used display from a 2017 and seeing if any video shows up (even if it's just to tell me that the vin doesn't match) etc..
Have I mentioned how much i hate proprietary electronics? absolute garbage anti-owner BS.
