Deviation, Variation and Heading Offset

[Derek - Raymarine - Moderator]

Hi bob423

Unfortunately the only way to adjust the heading offset is through an older SeaTalk control unit, there is no way to do it via the p70.

Unless you can borrow an older head to change the offset - which is stored in the computer, then the computer will need to be updated.

One point to note is that the autopilot doesn't care what the heading is - all it wants to do is steer straight - the heading becomes important if tou are using the pilot with an MFD and then heading is needed to orientate the boat icon and when engaging track mode.

The Eeprom is soldered on to the PCB and so replacement is an unlikely possibility.

Thanks
Derek
