E125 Auto Pilot Controls do not work after upgrade to 15.59

[lwitty]

I sent the S3 to Raymarine Repair and they upgraded the software to the latest version. The upgrade and bench test was reported as successful. I re-installed the S3 today and the behavior on the auto pilot controls on the E125 remain the same and are not working.

Again, upon initial installation of the E125 with the older version of Lighthouse, the auto pilot controls on the E125 worked as expected. Only after the update to 15.61 did they stop working (elapse time was about 2 days between original E125 install then the upgrade from 12.26 to 12.61).

What is the next suggestion in this troubleshooting process? The way my electronics are configured, I really need these auto pilot controls to work from the E125.
