I bought it used out of a Cirrus for a great deal from a radio shop. My mechanic and I installed it. He's an A&P and AI so we filled out the 337 as required and sent it in. However, since he doesn't deal with this type stuff regularly, he had me ask the radio shop what was required on the 337 to make it IFR legal. The radio shop told him that it would require a field approval from the FSDO. As it is, it's only VFR legal. Again per the radio shop. I also don't believe that the radio shop is an authorized Garmin Dealer. But I didn't ask. So now I have a VFR legal 430 and don't know where to go next. I'm also working on my IFR rating (85%) complete. And need to get this taken care of before I can take my check ride. The only thing I've found on Garmin's website is for a 430W. Nothing on a 430.

I just installed a used Garmin 430 (non WAAS) in my M20E. However, the radio shop tells me that I have to write my own manual and try to get it field approved for IFR operations. Surely he is uninformed and there is already an STC out there for this. I know I'm not the only M20E with a 430. Is no one using them for IFR operations? Thanks in advance for your help.
