I just put a Garmin 430W in my plane and had the software updated. I now want to be able to update the Nav Data card. I'm getting conflicting answers to my questions and so figured I'd post it here. For you 430W users, I've got what I guess is an older Nav Data card, it doesn't have the orange tag, it looks white. I've got a newer Jeppesen, Skybound G2 USB data base programmer. Can I program my older card? the directions for the card seem to say I can program cards from 2mb to 16mb which I think is all of them, even the non waas units. Any of you 430W drivers doing what I want to do?
