    Default How to patch unlock garmin img

    How to patch unlock garmin img.
    no need to generate *.unl file, this is nice if you have multiple units.

    put your gmapsupp.img in c:
    unrar the 3 files in c:
    now you should have those 4 files at c:

    gmapsupp.img
    garmin_unlock_script.bat
    GarminUnlocker.exe
    gmt.exe

    double click garmin_unlock_script.bat and wait.
    a couple of minutes into the script you have to press enter for the script to continue.

    download the files at:

    [Only registered and activated users can see links. ]
    [Only registered and activated users can see links. ]

    give it a try and let me know how it goes.

    --------------------------------------------------------------------------
    the script looks like this, very easy to edit for your own likings:

    md c:\s
    gmt.exe -s -o c:\s\ c:\gmapsupp.img
    del /q c:\s\*.mps c:\s\*.unl
    GarminUnlocker.exe imgset c:\s\
    gmt.exe -j -o c:\gmapsupp.img -m "Garmin Unlocked" -f 555,1 c:\s\*.*
    del /q c:\s\*.*
    rmdir /q c:\s

    Hello all
    I have just used it today with a GARMIN GPSMAP 421 and blue chart G2 vision map.
    Just a warning was displayed about marina file map but the result works fine on the 421!

    Now have also found "Fast IMG unlocker.exe" on the forum, I have not tested, this one should also works.

    Hope this works...
    Tell me if I do something wrong.
    1. Downloaded Garmin Bluechart G2 Vision VEU708L North Nrway
    2. Copyed it to C:
    3. Unrared garmin_unlock_script to c:
    4. run the bat file... (like alautre it displayed the warning on the marine map)
    5. copyed it to a sd card..... no other files than GMAPSUPP.IMG on card.
    Will this work when I install the SD card in my 421S ???
    can't try it until next weekend.

    These unlockers don't seem to work with GB Discoverer Full. One file is a Gig in size and the programs seem hang. So far I've not found a solution that I can make any sense of... There are rumblings I saw in a thread somewhere about a bug that is now fixed in Jetmouse V1.5, but I haven't figgured out how to use it with my map. All ideas and pointers welcome cos I'm pulling my hair out with this bloody Garmin product and feel it's more of a 400 paper weight at the mo!
