Deviation, Variation and Heading Offset

[bob423]

Thanks for the quick reply! I had the issue before I replace the old head which was failing with the new p70. I was hoping the problem was with the head and the p70 would correct the problem. As of yet, I haven't done the 720° circle to calibrate the autopilot with the p70 head.

I was looking for a way to enter the 180° offset directly but couldn’t find the screen on the p70 to use. I’m thinking I need to enter dealer calibration mode but I don’t see the instructions on how to do that in the users manual. Can you tell me how?

If the eprom is bad, then I’m out of luck, I guess, unless I could replace only the eprom. Is that possible?
