I’m using a Navio2, Arduplane 3.8.3, and an mRobotics GPS/Compass unit with an integrated HMC-5893 compass unit.

I hooked up the GPS to a serial port through one of the USB ports, configured a -B telemetry switch and it works well.
I configured the compass as #3 and external like I did with my stand-alone HMC-5893 units. I connect the compass port on the mRobotics unit to the Navio2’s I2C port.
The Navio2 detects the presence of the compass but it does not get heading from it. Mission Planner displays EKF compass variance alarms which is strange as external compass #3 should be the only compass in play.
Can you tell me if the Navio2 can support this GPS/Compass?
Thanks,
Paul
