Do you have the "zero" version or the one with the APM flight controller?

The APM version would have been advertised as Open Source.

Have you downloaded the mission planner software and connected to the computer? Which APM firmware version is it running?

The initial compass calibration for APM is done in the software. You can see the procedure HERE on the ArduPilot page.
