Ray Marine C80 Gives bad heading

[Jetmart]

I have a C80 that I have been using the last 3 years and thought I knew everything about it. It started giving bad heading & distance this season. Here is what it is doing. I will have a route with many waypoints. It displays the route as entered just fine. All waypoints are where they should be. It joins the waypoints with a solid black heading line as it should. If I folio this black line between waypoints using the picture of my boat there is no issue. GPS is accurately displaying the boat & waypoints. The problem is there is displayed a dotted straight line from my present position to my destination which goes across land - a straight line which does not follow the waypoints. The GPS is using this line to display heading info & distance info for me to steer to. My COG & SOG are fine as well. Any ideas?

The dotted line is always the active course to the next waypoint, so I figure your waypoints are out of order. You may have reversed the route if the last waypoint is now first.

Thanks. I think you may be right. I will have to try it on the way home after building a new route.
