I was slow trolling using my Navpilot 300 and all of a sudden it went haywire and steering g the boat into a circle. It wouldn’t take any commands so I shut the unit off. When I restarted it, it started up normal then gave me an error that it found that it couldn’t connect to processor check connections and contact dealer. When I got back to the dock I checked all connections and found nothing lose or abnormal. I went into the menu and checked the devices and it showed the pg 700 and the 1971 gps unit, nothing else. Hoping for some correspondence here or I’ll remove it and send it back to Furuno next week.
