Thread: How to backup Nuvi NV (region41) with sd

Read the first post again. Any device with a non-vol region will have it in either 41 or 154. Your result shows 'success' for rgn41 and 'error' for rgn154 so yours is in 41.

Im going a bit crosseyed with how chicken & egg this comes across...

I get:
1-Create a "Garmin" folder in an empty sd.
2-In Garmin directory create a directory named "Updater".
3-In Updater create a directory named as your nuvi HWID number, it must be 4 digits eg: 0971

I Do NOT get:
4-In the above folder copy Ldr.bin . What is Ldr.bin? It is your firmware boot.bin you can extract with RGN_tool

Ive got a nuvicam & Ive been peeking around on the nuvi all over to find boot.bin & no dice. I tried using the nuviCam_360.gcd file from garmin, but that seems to conflict with "your nuvi "personal" backup" since it came from Garmin & NOT from MY nuvi

MTP Mass storage & RWFS have both been enabled, yet Im still not seeing boot.bin anywhere?

You cannot 'see' the boot.bin, it's not part of the file system. It's a component of the firmware file, so open "nuviCam_360.gcd" with RGN_Tool (attached below) and save the first section as Ldr.bin. Look at the pic in initial post of how to do it.

Good ol' overlay filesystems... :/

Yea, that was about the only way that I COULD get visibility of that file -but somewhere they were saying that this is supposed to be content from MY nuvi, inclusive of licensing, serials, yadda yadda yadda?

The file GUPDATE.GCD is usually on-board in the (usually hidden) .System folder, but it's not always present. You can unhide protected system files and other hidden files and folders in Windows via Control Panel>File Explorer Options (or Folder Options depending on OS version)>View.

Excuse for dullness! Point 4 is not clear to me: Where to take me the ldr.bin file? Boot.bin, we receive by means of the RGN_Tool program, having pressed the SAVE button. But the program needs to specify something in the beginning?

please, where I can find a firmware boot.bin so I can extract with RGN_tool

Thanks all
