I have a 2020 Model X. The rear view mirror structure Houses the forward view cameras as well as a small ribbon circuit board. What does the circuit board control? The connector has separated. is It for the sentry function? Or does it help with how the cameras see?

Part of that circuit board houses a humidity/temperature sensor.

Oh very interesting. I seem to be experiencing problems with the cameras. I have tried calibration, but it has not resulted in the system working properly. It keeps telling me the cameras need recalibrating. I have lost the blind spot monitoring, as no other cars are showing up On the screen. I tried changing wheel size but that did nothing. There is a reset button option just below the calibrate cameras. What does that do?
