How to backup Nuvi NV (region41) with sd

**mong736** · 21st August 2013, 01:39 PM

So mean no way I can backup my Nuvi NV?
Actually, my device is working well. Just want to backup this file to be safe.

Yes, most probably you can't do it. Unless some other dumping command is found. But this is not likely to happen.

ok. thanks. think i better not to tweaks around with this device too much in case anything go wrong.

BTW, does this mean that i cannot clear non vol in Debugging menu or hard reset the device if anything goes wrong?

No it doesn't, as boot.bin's rrgn functionality has nothing to do with what you've just listed.
But clear non vol and hard reset are much weaker than restoring backups with rrgn/xrgn sequence.

I wonder if older versions of boot.bin for this device would support rrgn ?

Do you know any Garmin pages where SG/MY (and other asian) firmwares are listed?

What I do hate in Garmin is that their firmwares can't be downloaded in a unified way.

I search for SG FW like this:

Thanks, I wanted to scan firmwares automatically. Apparently, I can do this by parsing pages like this one
