The 400A can be used for LNAV minimums, however, LPV minimums, are not authorized. Attached is a page out of the 530W installation manual rev E.

Interesting! I have Rev K of same manual and it does not have that limitation. Nor does it have most of the autopilot interconnect diagrams.

"Note: Contact Garmin to remove VNAV limitations."

Talking with Billy today, engineer at Garmin, we can’t get LPV minimums with the 400A autopilot, LNAV minimums only. The 400B that is approved is a different animal compared to the 400A.

Rats. Tell them to certify the GFC500 for us.
