Anyone know where I can get these specific years or cycles? Or is there a way to update the info in the Garmin 430/530 desktop training app - which I know is a stretch.

Same for the GNS 480. All you need is any db file (you can just copy it off the card in the unit because it's just a standard NT filesystem on a CF card). They disabled the unit checks so any file will work.

Only one way to find out. Change the name and pop it in as I described earlier.So all I have to do is find someone with a 430 and make a copy of their most recent update and go from there?
I have a 375 and this what I am seeing will the atvn_db.bin.siff work?

What’s in the two subfolders?
The 430/530 update process is a bit weird. Special cards, special transfer hardware. As I recall from the one time I pulled it off a 430 update, it took a few tries to realize that the app-usable nav database was a disappearing file. It was created on the PC in a temporary folder during the update process, morphed into something that only the unit could use, and then disappeared. Getting it involved locating the temporary folder where it was created and grabbing it before it disappeared. You'd probably have more luck pulling it from the 375 or 650 update (although I've never done that).ldr_sys has a file called grm_feat_key_000.bin
The maintenance file is empty.
All going to be moot soon... The CFII I am working with for an IPC is real persnickety about my mastering the 430 as that is what is in the plane we're using. I keep telling him, once we're done chances are slim I'll never touch another 430 as I fly behind either a 375 or a 650. But, will keep the app on the computer to practice with during the long useless, boring, annoying, and uninformative 90 minute monthly company wide conference calls..![]()
