    GPI Files don't need to be unlocked.
    You can convert them back to a csv file to modify, except they are encrypted by Garmin

    You want to get unlocked something that is locked, and presenting only example (that is NOT locked) and not actual file that is locked ?!?

    If you really want help, present all information needed:

    What exactly it is?
    Where did you get it?
    What do you want to do with it, that you could not do (where do you want to use it)?
    Attach file (if it's not greater than 2MB) or provide link.

    This is info I got from
    ballebar?dateline=1265819580 Ballebar


    It's possible to detect FID (MapID), PID, RgnID and VenID by reading the GPI-file. Using a HexEditor is an advantage.
    The 5th byte shows an offset. Use this offset +9 bytes to find the start of MapId (2 bytes swaped), PID (1 byte), RgnID (1 byte) & VenID (1 byte). You will then take all of the 5 bytes and use them in [Only registered and activated users can see links. ]. You will of course also need the memory card ID (CID) or unit ID to generate a 25-char unlock code that works for your memory card or GPS unit.

    Example with 4 gpi files:
    mac5mr

    rijeka_tourist_guide.gpi (NOT locked, no need for UNL-file):
    DE 03 01 00 00 -> (Hex) 3DE, 1, 0, 0 -> (Dec) 990, 1, 0, 0

    Fodors_2008.gpi:
    84 03 05 01 00 -> (Hex) 384, 5, 1, 0 -> (Dec) 900, 5, 1, 0
    Use generated 25-char unlock code in "Fodors_2008.unl"

    6_34_safetycam.gpi:
    84 03 09 06 22 -> (Hex) 384, 9, 6, 22 -> (Dec) 900, 9, 6, 34
    Use generated 25-char unlock code in "6_34_safetycam.unl"

    MPFullEurope.gpi:
    84 03 01 01 01 -> (Hex) 384, 1, 1, 1 -> (Dec) 900, 1, 1, 1
    Use generated 25-char unlock code in "MPFullEurope.unl"


    Both GPI-file and UNL-fiile should normally be stored together in the "Garmin\POI" folder

    / Ballebar
