Hi, i need to legalize an EX500 installed on a PA-34-200T many years ago without a 337, according to the STC i need the AVMFD-079 and AVMFD-303 documents; i request this documents to Avidyne with no results, any of you can help me with this documents?
Looking for the correct installation of this equipment the only heading source that i can see in this aircraft its a KI-25A, is this a valid heading source?

I do not know about those documents, but the "KI-25A" is probably a KI-525A which is the indicator for a KCS-55A compass system. The KCS-55 was the standard of the industry for many, many years so I suspect it will be a valid heading source for any kind of equipment.
