    Guide How to backup Nuvi NV (region41) with sd

    How to backup Nuvi NV (region41/154) with sd



    To make the NV backup with sd:

    (Important note :NV backup is not the backup of Nuvi files , but it's the NonVol memory backup,it contains Nuvi ID, all your maps codes, probably your Nuvi registration date on myGarmin and first satellite fix etc. Everything is in reg 41, all in these few bytes.
    Note: In many newer devices, from 2xxx series 2014/15 onwards, NV is present in region 154 *See 'Update' Below.
    NV backup is your nuvi "personal" backup ,dont share it on public forums or you can risk someone clones your Nuvi)
    Do not attempt to load an NV backup from another unit to your own unit, even if the same model.

    NOTE:Nuvi 3560 SG/MY HWID 1521 boot.bin doesn't support rrgn command at all,so one can't dump regions from this device.


    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
    4-In the above folder copy Ldr.bin . What is Ldr.bin? It is your firmware boot.bin you can extract with RGN_tool
    Spoiler: RGN_Tool.exe
    [Only registered and activated users can see links. ]


    ipIakD1

    and rename it as Ldr.bin.
    5-So copy it in "XXXX" (nuvi HWID) folder along an update.txt made with notepad where you'll write this command :

    rrgn,41,1:/41.bin
    reboot

    reboot
    To
    rrgn,41,2:/41.bin
    reboot

    But this would be located on RWFS drive but not SD. I think you can find it there (in RWFS).
    6-Insert the sd in your nuvi, you'll see at boot a software loading message and nuvi will write your NV backup in sd. Let it reboot, shut it down, remove the sd and keep your Nuvi NV backup in a safe place.

    To restore it replace command with:

    Instructions:
    xrgn,41,1:/41.bin
    reboot

    *UPDATE:
    In newer MTP devices, 2xxx series 2014/15 onwards, NV is present in region 154 and the path to the card is again 2 so write:
    rrgn,154,2:/154.bin
    instead of rrgn,41,2:/41.bin

    Finally I could do it !!!
    Probe with other memory and I could get the bin of 6 mb approx.
    It was strange compatibility issue with my 2GB memory.
    Now I'm copying the contents to a secure folder on my PC for the case if ill need to restore it , can i do this? There are simple file or boot sector issue, etc? so I can re-use the memory again.

    You can certainly copy the bin files to a PC Folder, and you should do this.(backup is the whole purpose of the exercise)
    You can re-use the memory card for maps and other Garmin Files.(just delete all the files on the memory card or you can leave them in there if it doesn't bother you)
    There are no boot sectors or anything like that on your memory card only folders and files.

    Hi.
    Tell me please how to restore nuvi NV from this backup?
    I have a nuvi 1410.
    If I create a copy of NV on other nuvi 1410 with same preloaded card, will I be able to restore NV on my nuvi?

    Dont do this.
    You must use only your reg 41 becouse inside this region is your settings of chipset etc

    Restoring from One Nuvi to another is not really advisable and can cause Problems for You.
    This procedure is really for you to backup your own unit, just in case something goes wrong and you need to restore.

    Caty, it really couldn't be much clearer really that the opposite is also dangerous, but what do you think about maybe adding a note in Post #1 to that effect? For example:
    .........dont share it on public forums or you can risk someone clone your Nuvi, also do not attempt to load an NV backup from another unit to your own unit, even if the same model. Seek expert assistance if you do not have an NV backup of your unit.

    Thank you. I understood everything.
    But how to solve my problem?
    My nuvi itself was rebooted during movement. And was changed the model number from "nuvi 1410" to "nuvi 14xx" and disappeared inside nuvi the key of preloaded maps.
    Tell me, please. What do I do?

    One of 2 things:
    1. Turn to Garmin for help, because you have damaged your NV memory as I'm sure you already know. If the unit's out of warrant that will be expensive; or:
    2. Hope that someone with the knowledge is willing and able to give you that 'expert assistance' to help you regain your 'model number'. This should not be dealt with in open forum and you can only hope for a PM offering help.

    BTW, my tirade in the post above yours was not directed at you personally, but the potential for misuse of nv backups both ways is real.
