I've lost my radio, rearview camera and iDrive functionality on my 2014 m235i. Upon starting the car, the BMW logo appears on the big display, but this randomly goes on and off as I drive. Nothing else ever appears. It's either the logo or black. Everything else seems to be working (parking sensors, AC).

I've tried all the usual online "fixes/hacks," including:
1. checking fuses
2. holding the radio power button down for 20 seconds
3. holding power button down for 70 seconds
4. pushing the start button 3 times and THEN holding the radio power button down for 20/70 seconds
5. replace the iDrive controller knob
6. disconnected the battery overnight

I do have a digital analyzer (but am honestly not that familiar with it) if that helps.
