How long since you calibrated the magnetometer?
Bob is right, you probably need to calibrate your magnetometer. During this process pay special attention to ferrous items in the baggage area, rebar in the concrete (big no-no), and metal buildings within 200' of the aircraft. All of these may contribute to a poor magnetic model generation during the magnetometer calibration.
Fiddling around i found it is possible to manually correct the compass by adjusting the offset.
