Nuvi 2597 problems : Not detected with Garmin Express or Windows 10 / 64 bit
Hi There,
I've been struggling for a few days with two Nuvi 2597.
The first Nuvi plugged in Windows 10 / 64 bit could not see the Garmin.Why ? I have no idea so I could not update it ...
The second Nuvi plugged in Windows 10 / 64 bit COULD see the Garmin so I updated to the latest 8.80 Software and 5.08.11 firmware.
All was fine with the second nuvi I plugged and unplugged many times for a few days UNTIL i put a microSD with an unlocked western Europe map image with a gmapprom.img and a JCV folder with a D3090290A.JCV file
i knew i should have backup before inserting the microSD !! When I booted the Nuvi 2597 it now says : Cannot unlock maps / maps are corrupt and cannot be used.
I expected that since i had read about it I knew i was probably missing a step or two ... BUT
Now The second Nuvi plugged in Windows 10 / 64 bit CANNOT be seen by Widows or Garmin Express !!! ARGGGHHH !!! :-( It therefore won't update anymore I can still use the GPS but don't have acces to any files.
Can anyone please help I'm over my head with this one and I really needed this Nuvi 2597 badly for a trip to Europe :-(aztech 222 Reviewed by aztech 222 on .

Not seeing the device in "This PC" we normally would say this is a issue, but as one was seen by GE & your PC ,this might be a hardware issue. We assume you tried other USB cables
Lets look at the one that you could work with ,the second one.
This error is because later devices need to be Patched to use Unlocked maps.
We need to know the HWID from the garmindevice.xml as not all nuvi 2xx7-2xx8 are the same
<PartNumber>006-BXXXX-00</PartNumber>
<SoftwareVersion>000</SoftwareVersion>
<Description>nüvi 2597</Description>
So fixing your connection issue would be great.
But Highly likely 2077 as you told us the update was 8.80
Tell us what Hardware version on your device C4 ?nuvi 2xx7 and 2xx8 006-B1582-00 Release 5.50 nuvi 2xx7 and 2xx8 C4 006-B2077-00 Release 8.80

Unless you are a "New" member, having used the Thanks button regularly is the quickest way to get help.

My Hardware version is : V5 M4v3 8GB DS128 A5 BT MFi RDS
FMI 3.6
If you need any other info please just ask and I appreciate your Help .

This information is not useful, what we need is the HWID of the Device.
While this is almost certainly HWID = 2077, you need to be sure not to risk bricking the device.
In this Tutorial you will find the how, the what and the where to get this code:
About the Device NOT seen by Windows, the matter is surely Windows.
Try to install last version of USB Drivers (In attach)

You cannot Patch your device by guessing the HWID unless you are OK with a 50-50 chance of owning a brick.
You have a USB communication issue ,you have not been locked out.
Unpack the contents of this archive to a clean/empty FAT 32 Formatted SD card ,turn your device off(not standby)Insert SD card ,start the device, loader will appear for a short while then the device will start normally. Switch the device off ,remove the SD card and plug in to your PC ,your should now have a copy of your garmindevice.xml on the SD card. Open and report back the HWID
SD card kit for Garmindevice-xml back up nuvi 25x7 C4.rarLast edited by Garmin_Nuvi; 28th July 2022 at 03:52 AM.

Hi Firefox 58,
I realize you need the HWID but i could not get into the Garmin to read the garmindevice.xml BUT ... ;-)
yesterday night I was determined and put extra hours to fix my Nuvi 2597.
I had supposed that Garmin probably blocked my NUVI since it happen right after I inserted my unpatched micro Sd card but i had a nagging feeling it might be Windows 10 / 64 bit and you were right! It was a corrupted driver for the Garmin in device manager that corrupted itself right after I inserted the unpatched Sd : Conicidence ?? Anyways I got that fixed and now I was able to acces the Garmin and get the info ;-)
Here is my HWID : B2077
<Model>
<PartNumber>006-B2077-00</PartNumber>
<SoftwareVersion>880</SoftwareVersion>
<Description>nüvi 2597</Description>
Is there a tutorial to do the patch and whatever needs to be done so I can get the micro SD Europe map to work ?
I had tried gimgunlock-0.04 but that did not open in my Windows 10 / 64 bit
Your help is much appreciated . I guess I may just be able to use this nuvi for my European trip afterall :-)

Hi Garmin_Nuvi,
As stated in the post above , you're also correct it was a "USB communication issue" ie: a corrupted driver for the Garmin in my Windows 10 / 64 bit
Here is my HWID : B2077 obtained by reading the garmindevice.xml
<Model>
<PartNumber>006-B2077-00</PartNumber>
<SoftwareVersion>880</SoftwareVersion>

An SD Package (Nuvi 2xx7-2xx8 C4 (2077) fw8.80.rar) is ready
Before using gimgunlock.exe You MUST Disable any Antivirus, it is ALWAYS seen as a threat
