My m600 flew perfectly 3 days ago. Did a setup tonight and it said that the compass + IMU needied calibration.  Did the IMU first. When trying to calibrate the Compass it shows that I do not have any compasses. So when it says press Start, there is no start button.  
  

Anybody come across this and have a know fix. I have sinced updated the controller and craft.  
Im needing this fixed ASAP, right in the middle of a job.
Thank you.
