I have made 4 unseuccesful atempts to calibrate the IMU. Sems to always stick at 2/6. My Gimble has excessive vibration and I'm told that IMU calibration is the fix? I have updated to the latest firmware update.

Any thoughts?

Hi Gerard, could you please make a short video of the gimbal's vibration issue?
Have you tried a gimbal calibration?
Also, here is the video tutorial of IMU calibration for your reference.

Your Mavic is too hot. IMU will fail. Cooler the Mavic, the faster the calibration and warm up times.
The FIX:
Leave the mavic off for 2hrs. Let it cool.
Familiarise yourself with the GO APP and make sure you know how to navigate to the IMU calibration screen asap. Watch the video below.

Once cooled, find a level surface. Power the Mavic on and Calibrate immediately. Try not move or cause any vibrations in the first calibration. This should take the longest.

Once done, do the gimbal calibration.
