My third screen is coming up with message magnetometer calibration required. I have calibrated adahrs, the other screens dont give that message, the screen shows same heading and info, hooked up to same hub as others, will recognize both adahrs. Not sure what settings to look for, also not yet flying. Both adahrs show green & ok in SV setup. Resetting and rescanning SV info not helping. What would trigger this on one screen?
