    Unlocking Garmin GPS maps from an SD card

    Have an old 2007 Garmin Nuvi & am trying to upload an OZ map I bought off the net a year ago.

    When I put original the 2Mb Micro SD card into the Garmin it uploads the maps no problem. However when I use another 2Nb Micro SD card with the same 2 files copied on to it I get no joy. The maps upload successfully but then you get a screen that says 'Can't Unlock Maps'.

    Am thinking it has something to do with the formatting of the Micro SD card. The properties say they are both in FAT but I'n not so sure.

    Anyone got any ideas?

    Here's some screenshots of the situation below:

    The original working card is the 'Removable Disk' : H
    The copied card is the 'SD Card' : G

    (Both Micro SD cards are different brands if that makes a difference)

    You want some cloning software I'd say.

    I don't know any of the current offerings as I haven't had to clone a drive since DOS. Something like these might be what you're after though...

    I haven't clicked on any of the links though so I don't know if they're safe or whatever.
