Bearing 180 degrees

[RockBottom]

I have rdp-139 display. The course bar and bearing are showing approximately 180 degrees off is there a setting to fix this?

Have you checked this while moving at 3 knots or better? The RDP139 works off of COG (Course Over Ground) and COG is not valid unless you are moving 3 knots or better.

I will check the next time I’m on the water. Thanks for the reply.
