Speed source
Hi, I have an Evolution 200 autopilot installed on my 22 ft Almar boat. Type 1 drive pump, Seastar HC 5345-3 steering ram. Attached is the Diagnostic data for my electronics. As best as I can tell, all software is the latest.

My Autopilot has never worked very well - will do great for awhile, then starts wandering off path, etc. Often when I first start the autopilot, it will not control the steering unless I give it a nudge using the steering wheel to get it going in the right direction. I will try to attach a picture showing the p70r display - showing how far off course it is before I give it a bump with the steering wheel to get control started.

After searching this forum, it became pretty clear to me that one possible problem is the speed source. Turns out the pitot tube on my Suzuki was clogged so I cleared that this weekend. However, I noticed that I don't have any other choices to select speed - the SOG from the MFD isn't displayed under the data source list. But I can get SOG in a data box along with water speed.

In the p70r display, the only choice is "auto" and nothing shows up as a source. The calibration is unlocked. My compass variation is listed as 4 degrees.
