T&T: Auto pilot "hunting"

[Peter Bennett]

Contact Raymarine - you probably need new software in the pilot.

I had a similar-sounding problem with an S1 system last year, but only
in the track mode.  I complained in Sept 07, and they finally had
improved software available in June 08.

In my case, the pilot would do a 30 degree turn when the XTE exceeded
0.01 mile, and never did the small adjustments needed to keep the XTE
near zero. As a result, the boat continually zig-zagged across the
desired track.
