I have Axius gen1 and my autopilot used to work perfect. I did a serious stereo upgrade and now I’m getting a ccm:compassInstallationIncorr error on vessel view when going fast and autopilot won’t work. After slowing down for a few minutes it goes away and everything’s great. I upgrade the speakers and there is one starboard side right above all the axius components and my IMU is mounted just below helm really close to speaker as well. After thinking about it for months I removed that speaker and it seem as everything works great beside my heading in vessel view being off a little from magnetic compass. I’ve been out a few times and it works. Next I’ll re install speaker and see if problem comes back.
