DJI N3 Problem

[CrazyMonkeyFlyer]

I have been facing this problem of calibrating the DJI n3 board using the DJI Assistant 2 software.
Everything is calibrated except the IMU which is showing an error of magnetic interference. Please help me out with calibration. I have triwed it for more than 20 times at different places but failed to calibrate the controller just because of the same error popping up all the time which is the magnetic interference. Please help me out with the problem and guide me through the further steps.

You're probably going through the correct procedure, you just need to:
Go outside, away from any possible interference like wifi signals, hydro lines, etc
Remove your car keys from your pocket
Most importantly, no electronic devices such as phone or tablet in the immediate area

I have tried it in open space where no interference is there but i could not find any change in the IMU calibration. Is there any more possibilities of errors that is leading to my calibration error?

If you're in an open area, the only other thing I can think of is the magnetic field produced by the power wires of your'copter. Is your GPS module attached to the frame or is it up on a mast away from the frame as intended?

On the first go it was attached with the frame and the whole body, then i have tried the same without the frame and body only covering the DJI FCB and my laptop. Will there be any interference from the laptop or is there any connection with the transmitter receiver? The transmitter i use is OS10 channel one. Is there anything related or i can be sure that this isn't an issue for the calibration?
