Run as Administrator ,browse to your locked img, select and wait ( you can alternatively drag&drop a single *.img on FIU)
Please ,if you want to keep the locked version too ,first backup it .
Leave it work till it closes itself (CNEU or CNA may need 10 minutes to be unlocked-they're big!)
FIU now it's OBSOLETE, not updated since a lot and ,for now, wont be updated, It wont unlock new signed maps in new devices.
Consider to use instead: [Only registered and activated users can see links. ]
a newer updated faster tool can handle ,without any problems, maps with big and signed IMGs too
Fast IMG Unlocker 2.1

a new look and minor changes
(corrected sequence of subfiles in IDX)
Patched Unlocker- It works with CNNAM 2011.40
Added some texts on command-line screen
a little correction
FIU preserve map version and mapsource flag
added the possibility to drag&drop single img on FIU
It unlocks any name *.img
NOTE : If you run a 64 bit os it will unlock also Garmin GB Discoverer 150K Full Coverage IMG and maps with big IMGs (Garmin Unlocker will need 3GB memory to work) with other oses you can try 3GB Switch
Hi Catymag, could you please explain me how to rename the "gmapsupp.img" file if another file with the same name is already in the GPS ? (I think have posted the same question under a wrong section before, sorry for inconvenience)

You have to navigate to get to the good.

Catymag, does this "IMG Unlocker" means we do not need to use KeyGen software anymore ? Can we process the IMG file through "Unlocker" and then direclty copy into the device without running "KeyGen" ? How about .unl files/codes ?
It's a Windows software tool. Follow instructions in post #1. Basically to have the fast IMG unlocker and "gmapsupp.img" in the same directory and then run the application.
EDIT: Fast IMG Unlocker is now updated with another GUI. Also supports drag-and-drop of Garmin IMG-file. Using drag-and-drop will start unlocking directly and it's best to do this for a copy and have the original locked file as a backup.
