Thread: How To Get Your SD Card ID in Your Garmin Device

Hi

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.
2. Select "Garmin Mobile XT" or "Garmin Mobile PC" in the Software Product drop-down box and hit the Generate button below the “Select Software Product” field.
This will be the software unlock code, this is the code for the SD-Card you are using. Save the code as SW.UNL in the Garmin Directory of your SD-Card
3. Now enter your 10# (10 digit decimal) GPS Unit ID into the "Unit ID" field.
4. Select "Garmin Mobile XT" or "Garmin Mobile PC" in the Sotware Product drop-down box.
5. Select your Map Product in the drop-down box and hit Generate button below the “Select Map Product” field
This will be the map unlock code, this is the code is for the map you are using.
Save the code as GMAPSUPP.UNL (or whatever else you named your map, eg. FILENAME.UNL) in the Garmin Directory of your SD-Card.
Copy your Map as GMAPSUPP.IMG (or whatever else you named your map, eg. FILENAME.IMG) to the garmin directory and of you go.

If this is still to difficult just download UnlockGarminMaps.7z (also called GarminUnlocker).
Follow the instructions in the readme file and you don't have to mess around with any codes anymore.
Has work for me with any map I am using. I am using GPSMAP 78, MobilePC, MapSource and HomePort.

Hope this will help

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.

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.
Attached Card_ID.rar that reads correct CID by using Windows CE / PPC / WM:

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.
