Cool P,
I thought that's all I changed. Perhaps there was more? I don't know. I did change the size_mm but that shouldn't have an effect on the appearance or disappearance of switches I wouldn't imagine.
I did manage to get the CIVA working and it followed Way Points as it should. I did have some problems so I just wanted to clarify the configuration of the Sperry AP when interfacing it with the CIVA.

1) CIVA aligned-switch to nav.
2) airborne- both AP paddles on ( I switched to system A- don't know if that's necessary)
3) AP in MANUAL MODE
4) Heading select engaged
5) CIVA switch on AP pop-up turned on
Is that all correct ? My understanding in that the CIVA controls the heading bug.

I haven't played around with it enough to really understand it thoroughly but I just want to get through the basics for now.

Also, on the AP pop up I have only one engage switch. Should there be two, one for each Civa unit?
And what is the advantage of having two units? Should they be working  together with each other to deliver an advantage?

Thanks lot for your help on this.

Cheers,
Brian
