    Removing the card from the Garmin before flashing was actually a smart move. However, it looks as if your directory structure is a bit messed up. Maps cannot be stored in subdirectories beneath X:/Map/ but must reside in the X:/Map/ directory itself. Thus, X:/Map/North America.img is acceptable. X:/Map/2013.10/North America.img is not.

    "sd card root" refer to the drive of sd.
    so it's be. X:/Map/2013.10.img and X:/Garmin/xxxx.jcv

    I understood what you meant by "SD Card root". I simply call it "X" as it's quicker to type out than "SD Card root".

    In any event, 2013.10.img may not work because the firmware may treat it as a double extension. Rename it to 2013_10.img and you should be fine. Personally, since the name of the file can be anything, it won't hurt to be more descriptive, e.g. North America 2013-10.img.

    @lolypop000: since I got lucky flashing the wrong boot, but it work. Should I reflash with the correct boot Or just leave as is since it works. Thx

    Thinking about it, i don't think the flash ever go through nuvi 1450 when i flash the wrong boot. Y? Because when I click OK and pop up msg said no available update then I click OK again, and the flash just cancel itself. But Y I have Full JCV? Maybe nuvi 1450 already had full JCV since Garmin site stated.

    Then question arise. y my nuvi 1450 never had full jcv b4 coming to this forum. I think maybe the original jcv was only 49kb and new jcv is now 755mb.
    ====

    My other friend had nuvi 1300 and based on garmin site, no full jcv. I will see what's his chipset is, 0972 or 1104. If none of those then i guess he's just unlucky to have jcv.

    People, you can't run 1104 boot.bin on a device with 972 bootloader and vice versa. It's because of the totally different loading addresses of boot.bins (0x60000 for 972 vs 0x10040000 for 1104). boot.bin is not a position independent piece of code. It crashes very early if loaded at a wrong address.

    As it is boot.bin who is responsible for flashing bootloader, you can't accidentally replace 972 bootloader with 1104 one and vice versa. Doing so would require running update.txt script rather than just flashing an RGN file.

    Exactly the same thing is true for firmwares. You can't run 1104 firmware on a device with 972 bootloader and vice versa. You'll see the "system software missing" message in this case.

    So, cat2115, it's impossible that you've flashed wrong boot or wrong firmware. Even if you renamed the RGN file, it would still be impossible. The explanation must be somewhere else.

    UPD
    By the way, I'm by no means saying that you can safely rename RGN files. It could be deadly dangerous!
    But in this particular case it's safe because of the different loading addresses.

    hmm, i don't know Kunix but I download the wrong file from here and in the Updater folder, there's two files (110401000610.rgn & Updater.exe). My friend's nuvi 1450 all had 0972 and version 6.10. When I flash 110401000610.rgn, it just say, "No Update Available for this product". I click OK and it just cancel the flashing. I guess the flashing never happened and that's y his gps didnt broke. Very lucky... See screenshot. 2w2obhx

    But weirdly, his nuvi 1450 had full jcv which he never had it before. That's y I'm thinking of maybe his nuvi 1450 already came with jcv and i just loaded him with full jcv (755mb) in sd card. That's y he can view full jcv. His original jcv was only 50kb

    @cat2115
    All the features enabled by this flash in 1xxx series are in fact already available in 1450, including JCV. A 50KB *.jcv file would contain hardly any views, if any. If was probably a corrupt file.

    If it says "no updates available for your product", then, yes, it flashes nothing
    It has looked at the RGN name and extraxted HWID from there and compared it to the HWID of the bootloader.
