The 737 A/P is a custom one with CWS. The fsx default hdg is taken by CWS.   If you wish the third party (CIVA etc) to use the default hdg we'll have to remove the CWS. What do you need more, the third party or the CWS? Please vote.

CWS, CWS, CWS, CWS..........Ohhh, I forgot CWS. I would like to add that I do have a lot of flight sim gear too and it would be nice if we could all have what we want without taking away from anyone.
