Works fine. Garmin control head
with linear raymarine drive and raymarine rudder sensor. Yes as said if your not using garmin drive you need the sensor. Mines been great except I have developed an annoying interface issue. The auto pilot compass
glitches off by 15 to 30 degrees. In service
2 years just fine and now it pulls this stunt. I updated software
etc.. Now I will recalibrate again. Hope that fixes it if not. Well the compass
is kaput. The kid at garmin support was not well versed. So a tad disappointed. It still holds a course but the bearing line is whacked. Which can a confusing piece that mentally requires constant compensation. I absolutely hated the wire terminations on the ray marine
. Maybe they got better. Really hope that this compass crap clears on the next calibration. Anyone else seen this?.
