Mag Interference, Compass Cal problems

[Bukrub66]

I bought a used Mavic a few weeks ago. It has flown fine until about a week ago when I had a Gimble lock warning. I watched several YouTube videos and read many forum posts and decided to replace the Gimble ribbon. This fixed my Gimble problem but now I have a Compass Calibration issue. Whenever I fire it up it tells me Mag Interference move drone. It also tells me to move drone. It also says Compass redundancy switch. I have tried to calibrate the compas with no avail. Sometimes it will pick up satellites, other times it is in atti mode. Can't imagine I've done anything to mess up the Compass with the Gimble repair but who knows. Was gonna send it to a place in Dallas for repairs but then thought I would post up here incase it is something simple. Any suggestions?
