    Tool Garmin Asian JCV Tool v1.0

    The JCV files of the following Asian map products are firmware dependent. They only work on GPS devices sold in the corresponding country with localized firmware.

    City Navigator Indonesia NT
    City Navigator Philippines NT
    City Navigator Singapore and Malaysia NT
    City Navigator Thailand NT (Dual, English and Thai versions)
    MalFreeMaps NT
    MalSingMaps NT

    The attached tool helps to overcome this limitation. To use,
    1. Download and unrar the file from the attachment or mirror site.
    2. Backup the original JCV file.
    3. Drag and drop the JCV file to the icon of extracted GarminAsianJcvTool.exe.
    4. That's all. The dragged JCV file can be used on devices that support JCV now.

    To use the tool in a command line or batch file, supply the pathname of the JCV file as the first argument.

    WARNINGS
    • Use at your own risk. Follow the actual road signs if the JCV picture displayed is wrong.
    • No warranty or guarantee.
    • Don't use this tool on other JCV files than those listed above.


    Special thanks to forum member Cnfhbr for his great helps and tips!

    Nice work syzygy. Added to Tutorials & Garmin Tools Indices. Rep+ from me and the eternal gratitude of many .... Excellent Warnings/Disclaimers suggest a legal background [or school of hard knocks].

    syzygy and Garmin Asian JCV Tool v1.0 are not guilty! The same issue with original TH JCV take place too. The comment of karaoke above puts Master under attack...

    Not so. NA 3597 will have an error when used with any similar Asian JCV file. No one is attacking syzygy, we are testing and reporting only. Hopefully syzygy can find why the patched file THGLB.jcv is causing the same crash and reboot error as original unpatched file in NA 3597, but not in NA 2xx5 for instance.
