C80 magnetic variation
Hi,
I have a C80 MFD running v5.16 software and networked to ST60 wind, speed, depth, a i70, ST6000 Autohelm and 120 GPS sensor.
The C80 is set to display magnetic bearings. Each time the MFD is powered on the magnetic variation is set to 2 degrees W which is not correct for my area (Toronto). I can manually set it back to 11W and it is fine until it is powered down. When powered back up it resets to 2W. It does not matter if the MFD is set to manual or automatic variation, same issue. The autopilot is set to 43 degrees latitude for its variation calculation and the ST6000 magnetic display is correct.
The result is the MFD is always displaying the incorrect magnetic bearings unless the variation is manually changed at every power up.
Any suggestions what could be the issue?
Thanks,
Brian
