FYI...
When I had just left Bremerton today and moving at 2 to 3 kts I used the "Guide To" for a Waypoint I had selected just this side of the Agate Passage fixed bridge. To my astonishment after selecting "Engage auto pilot" the boat performed a slow starboard full circle before settling down to follow the computed course line. I thought this strange and cancelled the Navigation and performed the same "Guide To" configuration again. The same thing happened.
Knowing that the 5212's GPS heading will lag the Auto Pilot's heading which is made worse when traveling slowly I wondered if this circling phenomenon was caused by my low speed. So I increased my speed to 7 kts for a short while and then selected the "Guide To" again. This time the boat did not circle and immediately engaged and started to track the computed course line. 🙂
N.B. The slower you're traveling the more time the 5212's GPS takes to determine the heading the boat is making.
