I bought an F90BT in October. It has been working fine until now, especially after the 2.0 Update.
I started the car today, and noticed something strange.
While the lighting for the knob and two buttons worked, the screen would not turn on. About 5-10 seconds after the lighting turned on, it turned off and nothing was on on the F90BT.
I have tried turning on the car and resetting the system - I believe it resets successfully, the button lighting turns off, there are some whirring noises, and the button lighting turns back on - the screen remains off, and the lighting once again goes away in
