Recently my 998c SI navigation started acting up. The boat icon remains fixed and does not follow the heading indicator. If i move the puck then the boat icon will move on the screen. However when I'm traveling the heading indicator varies around the boat as i travel. The boat icon use to follow the heading indicator. I have the latest update. I have reset defaults. I have over 5000 hrs of use and feel like I have looked for any possible fixes without any luck.
Anybody have any ideas?
