    ? cannot ulock maps message - nuvi 2577LT

    Hello there

    I bought a Garmin nuvi 2577LT with North America maps. when I start the instrument I am getting a message "cannot unlock message". I rebooted the Garmin unit many times but no success. when I hook-up the unit to my laptop, I don't find maps in the unit but the space used in about 10gb.

    Appreciate your suggestions / valuable advise

    Have you registered your device at MyGarmin?
    You can retrieve your map codes and unlocking files in your device MyGarmin page.

    Thanks for quick response.
    although the devise is registered, unable to register maps.
    now what I have done is, I have followed the instructions from the link you have sent and located the .img files and unlocked using img unlocker. after that restarted the device and no more I am getting the message. now I need to go out and check weather the maps are working or not.

    will let you know once I test the devise on road.

    If you used gimgunlock or FIU it will be ok if the map is not corrupted, but I'd advise to retrieve your unlock codes and .gma on MyGarmin, or redownload the map from Garmin (best choice IMHO)
