Seatrial Calibration is the answer.
My Raymarine Autopilot ST600+ did the same trick on me today, it was showing exactly a reciprocal of the course steered, and worked as an basic autopilot but when asked to steer a route it changed course by 180 degrees!
Re-booting both the instruments and my Raymarine course computer (RL70C) did not fix the problem.
After reading this post I performed the "Seatrial Calibration" as described in the Owners Handbook, motored 2+ circles taking over 2 minutes for each, completed the deviation correction and then the autopilot allowed me into the "Autopilot Heading" alignment screen. Motored in straight line for about 1 minute then hit "auto" and the COG from the GPS was accepted as the heading.
Thanks to previous posts for the encouragement. I have no idea why this fault developed as the kit has performed flawlessly for the last 4 tears/10,000 miles?

Finally found the solution. Turns out the autopilot dumped the memory, and so had to be completely recalibrated. Dockside calibration, then compass calibration at sea with a couple of circles to get deviation.
The solution came from the raymarine help line while sitting on the boat.
Rebooting didn't give me any changes, so I eventually called the help line. After about 15 minutes they had it figured out and so all is now good.
Thanks for everyones efforts.

We've had a couple of similar episodes with out new Raymarine ST6000 setup... no plotter, just auto.
What I noticed is that in addition to the offest the heading scrolled the WRONG WAY.. ie a turn to starboard generated a lower heading (in degrees). Since this represents positive feedback for the controller, the auto just layed the helm over hard and stayed there.
It's happened maybe 2 times in the year since I bought it, and a 'reboot' cleared it each time. A pain, though.

Doug, do you have a cell phone? I find that calling Rayma-who-ever- they are called from the boat, during business hours, usually gets some fast free tech support.
Odds are this is a matter of some menu setting for "heading/inverse" or for putting the mag compass into calibration mode and then making a couple of 360's so it can redetermine north.
Lesser odds are that your friend somehow knocked the fluxgate sensor out of place, and popped it back in backwards. (G)

Have you tried rebooting the autopilot (i.e turn off and then on again)?
We had it happen to us that the autopilot did a doughnut (360 deg turn) in the middle of the gulfstream under sail at 25 kts of wind - a bit scary.
Once I got the boat under control the autopilot indicated that we were on a course of 90 deg while I was heading due west towards Florida.
M resourceful wife solved the problem by turning of the autopilot for 5 secs and then turning it on again. Worked a charm and never had problem since.
Also check for big pieces of metal objects that you may have placed close to the aitopilot compass unit...
