    No, unfortunately it's not possible. Read again the first part of my reply above, but perhaps my wording wasn't clear i'm sorry. '6xx cannot retrieve a backup of 41' = 'You cannot do a region 41 backup of a 6xx'. The problem's not to do with the SD card, I think the command is simply not present in firmware of nuvi 2xx/3xx/6xx or earlier SP units either. I recall that rgn41 backup was not possible until nuvi 2x5/7xx series. Backups of other regions can be done though in 6xx nuvis, ie. rgns 5, 14, 15, 16, 24, 34, 45.

    In an extreme case as an absolute last resort it is possible to erase 41 in a 2/3/6xx series to restore a unit to semi-working condition if rgn 41 is corrupt. The problem is that all registration and unlock code are removed from the unit in the process and that makes updating with purchased maps impossible unless they are purchased on an SD card to which they are locked. Unlocked maps can still be loaded to internal memory normally.

    One of our software experts should be able to write the command into the firmware to allow backup of 41. Who's up for the challenge guys?? ........ [chirp, chirp ...... chirp ....] ........ guys? .... anyone??

    Catymag,

    I want to upgrade fw from 5.8 to 6.2 on my nuvi 1300, but the flash process goes into a flash-reboot infinite loop.
    Neil recommended a backup then a hard reset. I'm having difficulty. (BTW does a hard reset always make a restore from backup necessary, or is this a precaution? I read a hard reset destroys all the personal data. I have backed up all the files on my nuvi onto my laptop. Will I have to copy all of it back onto the nuvi after the reset so I still have my address book?) Anyway, here's where I'm at so far.

    1) I have an extra SD card, but is not empty. Does this matter. It has plenty of room. Anyway, I created a Garmin directory.
    2) Inside Garmin I created another directory Updater. So far so good
    3) Problem 1: I run linux and can only read my nuvi 1300 as a mass storage device on USB.
    I have virtual box running xp, but it neither
    connects to the web nor can RGN_tool read hwid. The usb drivers from Garmin won't install in my virtualbox xp either.
    The part no from the GarminDevice.xml is 006-B0972-00.
    This is not a 4 character string. How can I get the hwid for the name of the folder?
    4) Problem 2: When I open the nuvi in RGN_tool, the best I can do is open the 4 .GCD files (one at a time)
    in the RemoteSW folder of .System
    Each comes up as external_data.bin. I can't find any other files that RGN_tool recognizes, so I can't find boot.bin
    So I've read this entire thread and I saw I need GUPDATE.GCD. I run version 5.8 but do not have such a file on my nuvi.
    I could grab the one off the nuvi fw thread as it has all the different versions. But how does that help, since it is registers
    in my nuvi we want to grab. Why would backup be needed if we can just download the fw anytime and use it.

    So I'm stuck on steps 3 and 4. Please help me get over these hurdles. I'm sure I'll have more in steps 5 and 6 if I ever get there.

    1. Find a PC running Win XP OS or later [forget using Linux even with a Win VM].

    2. Extract this onto a CLEAN microSD [i.e. empty]: [Only registered and activated users can see links. ]. It's made with v5.8 boot bin as ldr.bin, so it will work with your flakey 1300 [first double-check that it is definitely the non-MTK chip HWID 0972 - open the GarminDevice.xml from the unit's Garmin folder and look for <PartNumber>006-B0972-00</PartNumber> towards the start to confirm].

    3. Insert the card into your nuvi 1300 and turn it on, then wait until it reboots before removing the card.

    4. Check that you have 41.bin in the Garmin folder of the card and that it's not zero bytes [it should be 4096KB].

    5. Copy the entire card contents to a safe place.

    You only need to restore your favourites and any other personal data. Everything else with be unaffected after hard reset/clear non-vol.

    Neil,

    Thank you so much. Your solution worked like a charm. Backup went smoothly. Your suggestion about the clean SD card is spot on. It turns out all my trouble in flashing 6.2 was because I had a Map folder and/or other nuvi related folders/content on the same SD as the gupdate. As an experiment, I renamed all the folders by appending extra characters and making them inert to the nuvi. Then, before I reset anything, I tried the flashing with gupdate all alone in the Garmin folder. It worked beautifully. So my problem is solved. Thank you again for your help.

    Hey Neil, it's me again ;D...Got a question for you, does it matter or make any differences if I use the "http://download.garmin.com/software/nuvi34xx_GCDFile__820.gcd" to do the backup instead of my 3490's "GUPDATE.GCD?" Any pros or cons to either one?

    G'day. Best practice is to always use the firmware version which is running on your unit at the time to extract the boot.bin [ldr.bin]. If your current fw is v8.20 then the gupdate.gcd in .System folder will be exactly the same file as 'nuvi34xx_GCDFile__820.gcd' and so either can be used. Compare the hashes and/or file size in bytes [77,757,239 bytes].

    Upload your pack that you use for backup region, so we can see what go wrong.
    If you wish, you can [Only registered and activated users can see links. ]

    There is no pack. When I backup the region 41 the unit shuts down and there was nothing on the screen for more than 15 minutes.I tried to switch on bt it can`t I desided that it is bricked and opened it, disconected the battery and conected it again and after the powered on but there was nothing on the screen.
    That`s all. Is it bricked or not?
