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?

Moved antenna, still no change.

It sounds as if the AS GPS HS antenna may be failing ...
Do you have access to another unit you could test connected to your AS GPS HS antenna ...??
