QMC5883 GY-273 not detected for Skystars H7HD ArduPilot 3.7

INav detects and works with this magnetometer but Ardupilot cannot detect. Not sure if firmware file for Skystar was compliled with QMC5883 accidentally commented out?? Anyone else out there having success detecting the QMC5883 with Skystars H7 FC? Thx Jason
