    And at the end what are we searching for? Do we know a result? Do we know is it bounded to the nuvi ID or other nuvi number? Surely is connected to the FID of the map.
    You can just paste "81D8B8..." into your favorite hex editor, as "81D8B8..." is a valid binary form, i.e. 81 is the 1st byte, D8 is the next byte and so on.
    As far as I've seen in the firmware, GMA contains old-good 25-character unlock codes. But I don't know all the details. I've seen that GMA parser uses AES for something. I really don't know what for.
    We're looking for a way to forge GMA files. Or sign patched GCD files, which would much more useful for me.

    Well, as far as I know unlocked maps are not as good as the originals (some minor functionality is lost, I just don't remember which one exactly).

    @ roger

    You wrote "what's the point" and I gave my explanation why would someone need creating gma. Well, never mind.

    P.P.: We wrote together with Kunix.

    @ Kunix and ddabcd

    In fact, I repeat: what's the point? Until you get there, as recalled Kunix and you, to create or circumvent the GMA completely, we have this.
    In any case, it is certain that those who know how to get around the limitation GMA bring it to the attention of all. And perhaps rightly so

    And to all those who ask how to create a GMA answer: what's the point? Simply use the tools we have now. We can not do anything else. That's it
    For now.....

    Ok,ok...np

    Bye,bye

    Not true,in any case, nowadays we have good tools

    That's the point ! We're always looking for challenges lol , it's like trying to solve puzzles, sometimes useless, sometimes it makes sense.

    The GMA is not direct protection of map and other contents by and large. It is an means of authentication above all. Furthermore we do not know which "traits is in this snuffbox"...
    Garmin, how much is 30 pieces of silver for Judas today? Were they worthy for crucifix of GPSPower?
