GPS approach requirments

Hi,
My 7A has a 430 installed and coupled to my Digiflight AP. The aircraft is otherwise equiped and qualified for instrument flight.
Do I need an FAA cert and flight manual suppliment as would a certified airplane to be legal for GPS approaches?
Thanks,

Don Bodnar

If you're an EAA member, there's an article on their web site about equipping an experimental for IFR: http://members.eaa.org/home/homebui...a Homebuilt for IFR operations.html#TopOfPage
Sounds like you just need to follow 91.205, assuming your operating limitations are correctly worded.
