rrgn,154,2:/154.bin - exactly for your device because there is the right NV region (154) and it is addressing to SD card (2:/)

It's actually OT here even though there's a command in there to backup region 154 (NV on most modern devices) because the prime intent of that is for the command "xrgn,14" to write modified firmware to the device's region 14 (hex 0E) to enable use of illegal unlocked maps to which the device is not entitled, namely out of its OEM localized area. Both the modification of their firmware and their mapping data is a breach of Garmin's EULA. Further discussion here is unwise.

gupdate.gcd - �� .

xrgn,14,2:/Garmin/Updater/2586/0E.bin
xrgn,127,2:/Garmin/Updater/2586/7F.bin
xrgn,158,2:/Garmin/Updater/2586/9E.bin
- the same as gupdate.gcd but there are the separated instructions in the above-mentioned file plus each update component is present in the separate block due to its the purpose.

Do not worry it is Same old soup just reheated

If you mean in regard to backing up their non-volatile memory with these commands, no. The DS 55/65 run a form of Linux not the usual Garmin proprietary OS.
