IFD 440 to IFD 540

   Short question: Is the connector wiring on the IFD 440 the same as on the IFD 540?

Long form:  I'm wondering if there's an upgrade path from the 440 to the 540.  That is, if I install a 440 today, can I upgrade to a 540 later by just changing the trays and moving the connectors over?  Or does such an upgrade require wiring changes as well?

	They are very similar. Sharing a similarity on par with the 430/530 units. There will always be wiring changes. If nothing else, you'd have to move the grounds to the new tray. But as avionics upgrades go, it would be an easy one. Mostly just swap over the connectors. David Bunin

	All of the 430 connectors are identical in size, placement and function as the top connectors on a 530 and same is true for 440/540s. In fact, I have two 530 trays in my test airplane and regularly slide 540s, 440s, and 430s into those slots. When I place a 430 or 440 in the trays, I use a handmade spacer plate for the bottom half of the tray. The extra connector/pins that a 530/540 have over the 430/440 are a few extra serial ports and the TAWS I/O. As David notes, presuming your panel has the space, that is a very easy and quick job for an avionics shop.
