I downloaded the JVC file and followed Niels instructions(post #6 above) i.e renamed it to gmapsupp.img, unlocked it with gimgunlock(gimgtools-0.03-win32) and put it on an SD card in theGarmin root folder .
The Zumo 660 is not "seeing" the map (under map info)
Also downloaded the gmapprom version i.e 2871052.exe which also does not work following Neil's instructions
My machine is a Win 7 64 bit
Also tried Neil's instructions on a XP 32 bit machine with no Joy.
My Zumo software version is V3.5 . GPS version 2.90 and DSP version is 2.20.
Clearly I am doing something wrong.
Any assistance would be appreciated
Thanks Catymag and Smokefree. I could not find gimgunlock-0.03+MapSigPatch .
I did find and downloaded "gimgunlock.0+MapSigPatch.zip" at post #256 here : [Only registered and activated users can see links. ].
I assume this is the correct file.
Please note that the first mirror on post #256 may be a corrupt file as when you try to run it its says invalid Win 32 application . I did run it on a 32 bit machine and not 64 bit.
The second mirror file does not return this message and appears to run on the renamed gmapsupp.img .
Once run through Gimgunlock and placed into the Zumo 660 its is still not "seeing" the file .
The SD card reader in the Zumo is ok as I tired other cards and it reads their maps
One thing that I have noticed is that when one opens the zip file for the gmapprom.img and then copies it to another location (to run through the Gimgunlock) it does copy to the new location with a file size of 1*663*369*216 bytes.
The 7.zip programme however returns the following message: CRC Failed in Map\gmapprom.img. File is broken
So it is saying the file is broken yet is copying it to a new location? Is the file size correct or is it indeed broken? Could the gmapprom.img be corrupt?
The file runs through Gimgunlock as mentioned above but maybe Gimgunlock cant do anything with a corrupt file?
thanks for all the feedback so far but this one has me stumped!

@hobbype (and other members): CN India NT 2015.10 NT locked img file via zippyshare (5 parts).
- Un-RAR the gmapsupp.img file
- Unlock with gimgunlock-0.03+MapSigPatch (the one you found).
- Place on a microSD in the root folder named Garmin.

Thanks Smokefree. I downloaded your files and used your password to Un Rar using 7-zip.
Placed all the files part 01 -05 in one folder and tried to unrar part 01 first using your password.
I then received the following error message:
Data error in encrypted file "gmapsupp.img". Wrong password
Alos l tried the other parts and no joy
Am I doing something wrong?
I downloaded the 5 parts myself a few minutes ago, unzipped them using the password provided and all worked just fine.
So the simple answer to your question is: YES!
The instructions provided in post #15 are quite simple and not easy to misinterpret.
I suggest you try them again.
Hi once again
I think there may be a problem with downloading the files as I tried to download them all again. Still does not work however 2nd time around .
I suspect the files are not downloading completely.
As an example
part 01 :
1st attempt to download : file size 204 800KB
2nd attempt : file size 204 772KB
Part 02 :
1st attempt to download : file size 204 757KB
2nd attempt : file size 204 610KB
What are the file sizes of each part?
Is there a way around this discrepancy?
Sorry if silly question but why is there a "HERE" in the title - ie "City Navigator India NT 2015.10 HERE"
