I have had perfect pass stargazer in my boat for the past 12 years. It has always worked flawlessly. I just took the boat out of storage and it locked in a GPS signal right away, got up to speed an it engaged like it should. I drove the first pass through the course and it was locked on a speed but never started beeping and timing in once we hit the entrance gates. I remapped the course and ran it again and the same thing happened. I turned it off and back on and still the same. It is locked on the course and getting accurate coordinates. Any ideas on what to try to get it recognizing the course again?
