    Is it possible to convert Nuvi 1460 Sg/My version 2.10 to Nuvi 1460 TH version 3.0 with the same instructions as below? This version 2.10 can view Thai JCV, but there are many bugs, so I want to upgrade to newer version (convert to Thai firmware) and can still use Thai JCV. Moreover, if this is possible, would it be fine to use Thai V11 Duo map?

    1. Delete Gupdate.gcd from your Nuvi 1490 US.
    2. Backup your GPX.
    3. Copy th_TH.kbd , th_TH.glx and 006-D2225-00.bin to their folder.
    4. Downgrade your FW Nuvi 1490 US to 3.00 US by 1490 300US.rgn with Updater.
    or nuvi13xxand14xxseries_regionfileonly__300.gcd.
    5. Convert your Nuvi 1490 US to Nuvi 1490 TH by 1490 3.00 US TO 1490 3.00 TH.rgn with Updater.
    6. Reboot and checksum your Nuvi 1490US it will be 1490TH FW 3.00.
    7. Your Nuvi 1490 is not permanent firmware you can not update directly by original TH firmware
    but it work for JCV and Lane assist.

    instructions reproduced above.

    question:

    1. which directory to copy 006-D2225-00.bin to? there is no font directory in 1490
    2. updater refers to webupdater? but webupdater does not seem to allow me to choose rgn file on my computer to flash...

    You can try it !
    But remember to always use your original boot.bin

    Who says that the Thai Firmware has not the same bugs? A higher version number doesn't mean its newer or better.

    tom1807 is right !
    ie f/w for 1xxxTH swv 2.80 is not better than the older one.
    It makes 1xxx keep rebooting.

    For swv3.00 has no report like that till now.

    Default High resolution JCV picture.

    TSM v11 has a high resolution jcv file for 37xx.
    And this is for GarminAsus M10 too. (GarminAsus M10 with official TCN TH + High rosulution JCV contain the same data as of 37xx jcv file)

    Here is JCV pic from official jcv for GarminAsus M10 TH

    Thanks Khun Aekhong. May I understand correct that if I use original boot.bin this will help to prevent my Nuvi turn into a brick? In my case, what should I do for instruction no. 4 ("4. Downgrade your FW Nuvi 1490 US to 3.00 US by 1490 300US.rgn with Updater. or nuvi13xxand14xxseries_regionfileonly__300.gcd.")?

    If you need to go back to US3.00 firmware., you can...

    -Use RGN_Tool to open "original US 14xx swv3.00"
    -save to a .rgn file (without modified)
    -Use updater.exe to flash nuvi

    That's it. !!

    And yes., Your nuvi will be fine with your original boot.bin
    It may keep rebooting if .rgn file is wrong but it's easy to recover just use your original gupdate.gcd file using RGN_Tool to save to a .rgn to recover your unit.
