    You could probably use the hidden system menus. Don't know exactly how they works for GPSMAP 62 series. The previous key operated (no touch screen) Garmin units used press and hold ENTER while POWER up unit to start with system menues.

    I tried but not working

    I found this:

    "Does the Garmin GPSMAP 62/78 have any diagnostic screens?

    Yes. Press and hold [Enter] when you power the unit on and you will see a diagnostic screen. The GPS firmware version is visible through this screen."


    It show a diagnostic screen but no SD card ID.

    Dear Humble Beers

    "Jetmouse keygen is a brilliant tool, just a bit tricky to understand for some folks.
    1. Launch the keygen, and type in your 10# (10 digit decimal) SD-Card ID into the "Unit ID" field.
    "

    Jedtmouse keygen is very easy to understand and use but....
    unfortunately again my question has been completely misunderstood!

    You say to type in the 10 digit SD_Card ID....
    but the SD_Card ID discovered by the software and by Microsoft Checkdisk program is 8 digits, not 10.

    That is why I asked if it is a hex code that one can convert into the 10 digit code needed by programs such as Jetmouse Keygen
    Also, many hex codes are displayed reversed so that the first five numbers un-hexed into decimal are actually the last five in the 10 digit numbers.

    It seems that no-one on this forum can answer that question.

    Example of SD_Card id:
    e.g. micro sdCard
    Partitiion ID: 3461-6432 (8-digit number in Hex?)
    3461(Hex) = 13409 (Decimal)
    6432(Hex) = 25650 (Decimal)

    So the ID number to plug into Jetmouse is either 1340925650 or 2565013409.

    Just try it, if you think there are only two posibilities!
    I believe the first one is right.
    I cannot try it, because all my maps are unlocked!
    When you put it in the calculator (switched to Hex) and switch it to Dec, it gives the first result.

    It seems to be very hard to stop the spreading of the "urban myth" that a disk volume serial number is the same as a memory cards CID (128 bit Card identification number: individual card number for identification). I've tried many times to explain that it doesn't work that way.
    The CID is permanent in the memory cards internal register. The volume serial number changes when the volume is reformatted.
    There's also tools to change the Volume ID (volume serial number). If that worked to change the CID then everyone could easily clone a Garmin map from one memory card to another. No such luck with the volume method though.

    The tool mentioned for changing the Volume ID:

    Introduction

    While WinNT/2K and Windows 9x's built-in Label utility lets you change the labels of disk volumes, it does not provide any means for changing volume ids. This utiltity, VolumeID, allows you to change the ids of FAT and NTFS disks (floppies or hard drives).

    Usage: volumeid <driveletter:> xxxx-xxxx

    This is a command-line program that you must run from a command-prompt window.

    Note that changes on NTFS volumes won't be visible until the next reboot. In addition, you should shut down any applications you have running before changing a volume id. NT may become confused and think that the media (disk) has changed after a FAT volume id has changed and pop up messages indicating that you should reinsert the original disk (!). It may then fail the disk requests of applications using those drives.

    If you have a Windows Mobile, Windows PPC or Windows CE unit you can try this tool.

    Some of this was covered by the last post, but since I started already, with apologies...

    Collection of random observations:

    I don't think that the checkdisk id is what you are looking for. That is a volume id generated by windows when formatting a new medium. The SD card ID is surrounded by secrecy for obvious reasons. The specification for how to access the code as part of the CID is on the SD card official website, but no help if you aren't an engineer.

    This ID is harder to find. There are internet links which look like they find the right id but actaully don't seem to work on current OS versions. I found my SD card ID by putting the card into a nuvi 250w and pressing the battery icon for 10 seconds.

    There are other ways but I'm still working on that.

    If you can find the correct SD card ID as 8 hex chars then you simply enter the whole 8 chars into windows calculator and convert to decimal which will produce 10 decimal digits, which would be the number required to decode the card. Splitting the number into two sections and hex->dec converting and then concatanating produces an incorrect result.

    So, not a lot of help, but just to save you time looking on the wrong track. At the end of the day, it can be done. I have done it.

    Dear All

    I have a GPSMAP78 which I use for Marine navigation. There are many ideas on how to get the SD Card ID, but none of them worked for my GPS, (by the way, it uses same BIOS as GPSMAP62). Unfortunately there is no simple way of retrieving the Card ID by software. Some gadgets like even mobile phones are able to show the Card ID, but if you don’t have the right one you are busted. The only way I could get the SD CARD ID was by installing Garmin MobilePC. Once Mobile PC is installed you can go to Settings-About and it will show you the Card ID of the Card inserted in your PC. This worked for me, but only for the first ever Card inserted. Subsequently inserted cards all showed the same ID number which was incorrect. So if you want to try use the card you really want to use.

    1. Download Garmin MobilePC
    2. Install using MAIN.msi (if using setup.exe it will look for previous version installed and terminate if not found)
    3. Start MobilePC with SD Card inserted
    4. After starting up it will ask if the purchase included a GPS, click “Yes”
    5. Next question is, Connect or power on GPS, click “Done”
    6. Now click “OK” and “SKIP”
    7. Click “Yes” at the next question (Some aspects will not work and so on)
    8. Now click “I AGREE”
    9. Go to Settings and then click ABOUT. On top you will see Device ID: 10 digit number, which is the Card ID of the SD Card inserted. Unfortunately if you change your SD card it will always show the same number, at least in my case. So try with the right card first. At least you will get the ID of one SD Card.
    10. Do not install in Trial Mode since it will give you a Software ID, not the Card ID. If you did by mistake, go to C:/User/Username/AppData/Roaming/Garmin/GarminMobilePC and delete the contents of this folder. Now you can try again

    Uninstalling and reinstalling MobilePC did not make a difference. I deleted all traces after uninstalling but it always came up with the No. of the very first SD Card inserted. Maybe someone else knows how to do this

    Default Memory card CID register reading

    @HUMBLE BEERS

    You have already described your GMPC and SD card experience [Only registered and activated users can see links. ].

    It's also already answered [Only registered and activated users can see links. ] with the following ...

    Garmin Mobile PC uses a "Software Unit ID". That ID has absolutely nothing to do with memory cards and their CID. The software unit ID is calculated at installation time for your specific PC installation.

    Garmin Mobile XT for mobile phones can read the memory card CID register.

    There's a lot of different SDK with API calls for mobile units and PDAs to read the CID (128 bit Card identification number: individual card number for identification).
    It's also possible to use a API call in Windows to read the CID. That will not work for memory cards mounted in a USB memory card reader. Only memory card readers with PCI, PC Card, Card Bus interface etc. will have the possibility to forward the API call and only if the driver supports the API call.

    Hello Ballebar

    Garmin Mobile PC uses a "Software Unit ID". That ID has absolutely nothing to do with memory cards and their CID. The software unit ID is calculated at installation time for your specific PC installation.
    Maybe you are not listening, but you certainly have not explained anything.

    If MobilePC with the Garmin GPS Package is installed and Maps are on the GPS it will give you the Device ID of the GPS. Activation will provide an unlock code for the Device ID of the GPS.
    If MobilePC with the Garmin GPS Package is installed and Maps are on SD Card it will give you the Device ID of the SD Card. Activation will provide an unlock code for the Device ID of the SD Card.
    If MobilePC Software version only is installed (using non Garmin GPS) it will give you a Software ID. Activation will provide an unlock code for the software.

    I am aware that Garmin Mobile XT for mobile phones can read the memory card CID register, and there are also many application that can do so on mobile phones and PDA's, but that is not what I am after, I surely don't buy a phone just to read a number.

    Cheers

    Followed exactly your procedure from post #37 and it doesn't work. ID created by Mobile PC is different than card ID displayed by nuvi.

    Actually I agree with Ballebar, your procedure doesn't make any sens. Mobile PC doesn't use SD cards at all.
    Thanks, Kanopus
