    I think the team is in order (no gaps)
    I also think that it's in the memory card, but I have tried 3 different memory cards!

    After inserting the memory card you get this kind of splash screen and all...

    Let's see if it can dump another known region or this is a generalized problem. The logo/splash is located in region 16 and should copy without problem. Please follow the procedure behind the spoiler exactly:
    Spoiler:
    • Ensure the nuvi is completely OFF, not just in standby. Hold the power button down until you get the prompt to turn it off.
    • Extract this RAR file directly to a CLEAN microSD card: [Only registered and activated users can see links. ]
    • Power the nuvi on by connecting it to a power source rather than using the power button (don't use a PC as power source).
    • Wait for it to finish and check the card content, there should at least be a new file 16.bin in the root.
    • Post the content of update.log file if 154.bin is not also present.

    Does that mean that you've given up?

    Or that you're now able to dump regions? If so, do you know what the problem was?

    Hi all! I've got Nuvi DriveSmart 60. Which NV region should be for it? How NV region depend on device model?
    Thanks in advance for reply.

    Read the update in initial post. All recently released models have NV in region 154, and also if it has a hidden RWFS partition the path to the media card is '2' not '1' as in earlier non-RWFS devices.

    Hi!
    How know if for one Montana 680, command is:

    rrgn,154,2:/154.bin
    instead of rrgn,41,2:/41.bin


    or

    rrgn,41,1:/41.bin
    reboot

    Thanks in advance

    @quebec001
    Three points:
    • As said in Post #227, if it has hidden RWFS partition, the path to the card is '2' not '1'. Using '1' will write to RWFS in such a device.
    • If region 154 is populated then either (i) region 41 is empty (or even absent), or (ii) it duplicates region 154.
    • If it has an RWFS partition and writes nonvol to only one of 41 or 154 it will use 154 for sure.


    I've not got access to a Montana 680 to check but I'd be surprised if it's not an RWFS device. You can easily check that on the device: Touch 'Speed' field on "Where To?/Map" page. Hold center of speedometer for ~6 seconds to enter Diagnostics Page and scroll down. If 'RWFS Settings' is present then the card's path is definitely '2' and nonvol region is 154 so just use "rrgn,154,2:/154.bin". You can alternately access that page by holding the top right corner of the Volume page in modern devices. Montana may be different.

    Regardless, there's no problem to write all possible combinations as commands:
    Code:
    Please Login or Register to see the links
    If you do that with an RWFS device and both regions contain the nonvol you'll end up with 4 copies of nonvol, 2 on the RWFS partition and 2 on the card. If 41 is empty or absent you'll have only one filed BIN in each of RWFS and card and the other 2 commands will return 'error' instead of 'success' in update.log or there will be an empty [zero bytes] BIN file also. If the path '2' isn't valid then you'll only have one or two bin files on the card. This is a copy of update log from a nuvi 2797 which got 4 bin files, none of them empty, all 6,422,528 bytes:
    Code:
    Please Login or Register to see the links
    If you do have that don't forget to remove any backup 154 and/or 41 BIN files from the root of the RWFS partition. In such a device you should only keep the 154 BIN backup as although the sizes may be the same there can be slight differences in the data and flashing a copy of 41 to 154 may prove very problematical.
