You must use MapSource Special, then Jetmouse UnLock works

I've now downloaded the latest version of City Navigator Europe NT 2011.40.gmap
The following files are
006-D0323-14
City Navigator Europe NT 2011.40.gmap, in this file is CNEuroNT_2011_40_mdr og Product1 and I000093D.TYP, CNEuroNT_2011_40.mdx, CNEuroNT_2011_40_trf.trf and Info.xml
CNEUNT2011_40Update.msi
USB_64.msi
Disk_32.cab
Disk_64.cab
USB_32.msi
Disk1.cab
Can there be a detailed description of how I install it on a nuvi 660, it should be in ROM
I've done it I've downloaded mapsource 6.16.3 usb driver version. Is this the right version.
So I downloaded a reg file is installed.
Are these programs place a particular place or it does not matter where they are accessed from.
What I have done is to run CNEUNT2011_40Update.msi
The present program in c / program data / maps / Garmin / City Navigator Europe NT 2011.40.gmap
in the same folder I have placed MapSource.exe and InstallFIX.reg
I install the reg file first then I open the map source.
The map source for me a window with locked map detected, I press open maps.
So I press the unlock region but I can not open anything, have tried to put the code from JetMouse into
Nothing happens. What am I doing wrong
