Ship icon not pointing correctly

[Sail Me]

1871f, my ship icon suddenly is not pointing in the correct direction. Help?

do you have a sat compass?? any speakers or magnetic fields close to it or the unit ?

Do you have a heading sensor connected? If so what is your heading source set to. Vessel icon orientation should be following what your heading sensor is sending. If there isn't a heading sensor then the vessel icon should follow COG if you are doing 3knts or better. Could you send another photo of the entire screen and data box showing?
