Final Approach
Correct, you can take a card from one 430/530 or 430w/530w to another and back without issues. I was told by Garmin the the GTN cards and downloads are unit specific, in other words, they "fixed" that problem.
Thanks. I'm cleared up on that. My planes will each have one 430w. I can update either card in either plane, and swap them back and forth. But not both cards in both planes at the same time. I knew that, but my real question was if each card was proprietary to each unit specifically.
Answer is NO.
Any 430 NAV card will work in any 430, any time, with any update. Thanks guys....
And that was a good tip about the second subscription with a buddy ....
Alright! I don't have to buy another sub to fly my 180, or my RV8 current.... I can't stand myself sometimes ....
