Thread: Guide Unlocking Garmin MapSource City Navigator maps

Hello all,
Following my collection of Garmin GPS I just acquired a 276c. Updated to 5.70
It came with City Navigator 2008 and 2009 non nt original cds.
In a windows xp sp3 32bit machine I installed them, original code and no chance of unlock.
After some hours on old posts and specially this, found the map ids, found my id, used jetmouse and used Mapsource patched and with protected garmin toolkit, all is unlocked and I see them on mapsource.

When I transfer to the 276c via usb using mapinstall (4.0.4 patched) it says on the device it can't unlockfile.
Any one from the old times that have a solution?
Keep in my I can't acess the contents of the datacard on the 276c, since I don't have the datacard reader. I can only send new map to it.

I know I can use osm and I also have been playing with it, but would love to check it how it was before, and this will serve for a garmin quest that is on the way also.

Have a great day
