Just completed a flight where I put the autopilot source selector on AB, HDG switch on, and confirmed that the CIVA will drive the heading, as suggested above by Dutch.

Version 2.6 is a great improvement.  Routinely can fly with Active Sky Next, Plan-G, and FSX Fiber Accelerator all working perfectly on my 4-monitor system.

As mentioned elsewhere, I have not yet found a way to view the Autopilot easily at night by clicking on the icon because it is very dark.  And when using the animations icon, selecting either the air stairs or the service door causes the main door to open/close.  All very minor details.  But this is a very complex aircraft, and Captain Sim has created an outstanding simulation.   :D :D
