What version of the code are you using? And how have you attached the compass?

I am having the same problem, I even bought a new compass/IMU

 

I am board mounting the compass and using .39, I have seen a lot of talk about broken compass's here so maybe if someone acknowledges it it would save some people the cost of buying a new compass/imu.

Load the APM code, which has the latest compass drivers. That will confirm if your compass is working right. 

 

We'll be posting updated ArduCopter code (2.0.40b) this weekend, with updated compass drivers.

Today I get a new Compass von Sparkfun and now all works perfekt in CLI and HUD. Tomorrow I will make a testflight with version 39b and will test the Auto mode.

 

Cheers Michi

Now I can see the data in the flight Diplay

 

I hope that this problem is solved in the 40 version

hi peter, may be the compass has gone. i had the same problem on APM2.12. I removed the compass PCB from the arupilot shield and found that the main chip had come off the PCB. i do not know how. i bought a new one and replaced the old one and everything was fine. i want to get it changed by the supplier since the chip came off without applying any physical force. good luck and happy navigation!
