Thread: Thailand Streetmap Eng NT+THAI V11.00+JCV+ DEM+ Thailand 3D Building

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

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.

Sorry for my unclear question. I mean do I need to downgrade my 1460 SG/MY FW 2.10 to 2.00 or I just ignore this instruction no. 4 and go to no. 5 right away by converting my Nuvi 1460 SG/MY to Nuvi 1460 TH by 1460 2.10 SG/MY TO 1460 3.00 TH.rgn with Updater?
