I had the same type of problem a few times with my sport pilot plus unit. As it turns out the problem was easier to fix than you may think. First of all, Make sure that all metal & steel parts such as tools, spoons, knives are not within 36" of the sensor in the middle of the boat. Also, do not use cell phone within 36" of the unit. All these items will cause the compass to go off coarse. These items within 36" of the compass will cause major steering problems and cause all kinds of beeping sounds. It is the same concept as holding your cell phone or storing your cell phone on the boat dash near the standard boat compass, it will throw your compass out of wack. The magnetic field in the center compass sensor is very sensitive to these types of items. Sometimes we don't even realize the items are close to the center compass. Anyway, for those of you guys who are having this type of trouble with your auto-pilot, give it a try, I'm sure you unit will function properly once you get the 36" clearance. Hope this helps, I know it did for me. Regards, Steven
