    It seems that the Chinese Firmware doesn't have the icon form keying the waypoint. Maybe I couldn't find it. In SG have this function.

    Looks like the file was delete!!
    Is the "updater.exe" the same as webupdate that can be downloaded from garmin website?
    I just got nuvi 1490T and try to change its OS to enable Thai JCV.
    Now I think I have rgn file ready, but don't understand how to flash it with rgn file in pre-boot mode.
    Could you pls give more detail on this step?

    Hi all!
    I was trying to change firmware of my 3790 to Sg/Mal but none of the attempts was succesful :/
    I was doing by instruction step-by-step with version 2.30 and 2.50 with no result.
    Device is working properly but info shows still 3.60 "european" version and I didn't noticed any changes in software and/or funcionality.
    It's just looks like firmvare remaining unchanged.
    Can anybody faced something like that? Is there any solution?
    I will appreciate any help or clues.
    THX in advance!

    Maybe you could write down the steps you made, then we can know where is the problem.
    Converting to SG/MAL FW 2.50 seems not so easy anymore. 2.30 is still possible

    Is your 3790 US ?

    3790US Hwid = 1101
    3790Sg Hwid = 1288

    After flash to Sg/My
    For RGN_tool v0.44
    Garmindevice.xml will show hwid= 1288

    For RGN_Tool v0.60
    Garmindevice.xml will show hwid = 1101

    For software version ., it will show 2.20 or 2.30 (Always :: if you didn't edit f/w by manual)
    If it shows swv 3.60(without manually edit) ., it means your unit did not be flashed by mod .gcd

    I guess you used a mod .gcd file
    and will not be flashed to nuvi if swv is the same as current swv in unit.

    So you need to override swv to lower or higher than swv in your unit for .gcd file.
    But you can use any swv number for rgn file.

    If success :: at least you will see POIs Icon on map.
    Please give more detail what you did and failed.

    updater.exe is not webupdater.
    The other way to convert your unit without updater.exe is to use RGN_Tool to save your rgn file to a gupdate.gcd file ., remember to override swv to same number both boot and fw_all.
    and not forget to delete a gupdate.gcd within .system in your unit.

    Place gupdate.gcd in sd card\garmin\gupdate.gcd
    turn off unit --> insert card--> turn on unit --> begin flashing.

    But I advice you should have updater.exe because you need this tool for recover nuvi if you get in problem ie rebooting.

    All I know is 3790us can convert to
    Sg/My 2.20
    Sg/My 2.30
    CHN 2.20

    and no one can convert to
    Sg/My 2.50
    Taiwan 2.10

    Don't say no one Maybe not now, but I bet someone will find a solution.
    Remember, in the beginning there it was not possible to flash back to US Unit, until PouchX found a way.
    Happy New Year my friends
