    Thanks
    Sorry,no you havent read with care or you should have understood why, maps with FID greater than 2200 are unauthenticated in your device , use unlockers as explained. Read it again.

    You can unlock in your etrex maps with FID smaller than 2200 with the .unl file, but all the maps from Garmin since almost 2 years have FID greater than 2200.

    In any case, what's the point? You have the tools to unlock the final .... that's more than enough

    Bye,bye

    No. Just Garmin can build .gma files, till now nobody could decrypt these files ,even because ,as Roger wrote above, we can cope with it

    In fact, we can decrypt GMA files. Firmware does it, so we can do it also. The problem is, we can't forge them, because they are signed with 2048-bit RSA and we don't know the private key.
    But here is the public key below. Maybe someone clever can break it

    UPD:
    Btw, here is the public key, which is used for GCD signing (2048-bit RSA also).

    @ kunix

    Kunix, can you make it in binary? Maybe it would be easier to figure something out.

    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.

    @ roger

    If you are a map developer you can make money from that. Not paying to garmin. But in general it is stupid. Just like making a software for iOS and not paying to Apple. For example.

    Sorry....I'm not a software developer, even maps. I can make 2+2 and not always
    I'm sorry but I did not understand much the meaning of your sentence. Perhaps because the translator on-line has its limitations (like mine)

    What I meant in my post is that the GMA does not have to worry (for now)
    In Italian language: discorso di "lana caprina"

    Bye,bye
