   2007 Cirrus W/Avidyne MFD,PFD & DFC90 dual IFD440
After the installation of dual IFD440's my rock solid DFC90 is no longer performing. If I enable the DFC90 "Straight & Level" button the AP sets up a level attitue and a 500' - 200' decent. I tried several times and go the same outcome.

Any ideas?

	This sounds like an unrelated issue to the 440's. The Straight and Level feature on the 440's does not reference the GPS at all. Did the shop that did you installation change anything other than the 430's to 440's?
