December 26, 20205 yr Strange as I can update the original 430 simulator of Gramin still with files from a GTN650 database: Copy the following files ldr_sys/avtn_db.bin -> worldwide.bin bmap.bin -> basemap.bin terrain.odb -> terrain.odb

It is also possible to use the GTN trainer database which is newer than the 430 trainer database. Then use the equivalent files. Edited January 31, 20215 yr by PeterBremer

Yes it does at my installation: C:\ProgramData\Garmin\Trainers\Databases\avtn_db.bin Just copy that one for the 430/530 worldwide.bin Could be that avtn_db.bin is for not-US only. Am not sure. The trainer insstalls for both US and non-US so expect it should be there.

Could be, but something similar would be needed for a worldide database of the GTN , nav_db2 is not sufficient I expect. For some reason the real GTN needs both, so I expect the trainer as well because that is effecytively the same as the real thing, and I found out that the avtn_db works also for the GNS. But if you really do not have it I am afarid I can not help with that one.

Actually it is... 😉 My understanding is that if you have a subscription, you get both the GNS and GTN formats. The GTN Trainer does come with two databases nav_db2 and nav_db2_grm.. but neither of these are in the GNS format.. Edited January 31, 20215 yr by Bert Pieke Bert

Strange you would get GNS files with a subscription as well if you did not pay for it. The size of that file is different between the GTN version and the file, somewhat smaller, as you get with a subscription for a GNS.
February 2, 20215 yr Garmin has introduced a new DB format (ADB2) which is no longer compatible with the previous one. However, it seems the G500 Jeppesen DB works with the GNS as-is. More info p3 here: http://static.garmin.com/pumac/190-01464-00_C.pdf Quote Starting with G1000 GDU version 15.10 and G2/3/5000 GDU version 6.50, Garmin began supporting a new format of the Navigation database known as ADB2. The ADB2 filename on the SD card is “nav_db2.bin”. G1000 GDU software versions prior to 15.10 and G2/3/5000 GDU software versions prior to 6.50 only support the ADB1 database format. The ADB1 filename on the SD card is “avtn_db.bin”. Database update tools will program both versions of the database onto the card and the avionics will use the database file appropriate for the system. Edited February 2, 20215 yr by RXP

Nott only for the G1000 GDU but for the GTN650 Garmin supplies both formats 'avtn_db.bin' and 'nav_db2.bin' at the same time. Possibly to do with different firmware versions in the field. For the GNS530/430 cards it is slightly different. For those can be written to an USB stick with a program like Win32DiskImager and then the files can be read.
