Thread: How to modify nuvi firmware for supporting a new TTS voice.

burachat .,
Now you helped me to show everyone can do it.
The last one thing I'll tell you is "Somsri is not real" ., I just said for the example.
I will point that everyone can apply my example to do with real TTS voice.
You are the first one.!!

Oh I see ,
Well , I can ensure that everyone should be able to do this after following your great instruction on this thread.
I don't have experience on doing this as well , so thank you very much for the guidance .

Appreciate it .

Try to change D2785 --> Dothernumber and then you will get an answer.

Dothernumber with 02? One more question, where should we put the line. Just replace with other voice or key in at any place?

ie D2785 --> D8888 or any number you want to try .
You have to point where is TTS voice in fw_all., so I seek for "Jill" because it's a TTS voice.
You should replace other name at start point of original TTS voice that be replaced.
You can compare where is the point should be replaced by picture in post No.1

Rem :: Don't worry if you use original boot.bin
Your device will always boot up even you make a mistake in fw_all
If you get a rebooting problem ., just flash nuvi with RGN from original firmware.
You can make a rgn by RGN_Tool.
Open original firmware and save to a rgn file., That's it. !!
After that your nuvi will alive as normal again., I promise !

Now I try to modified 765 TW swv 3.10 to use Thai jcv file.
My 7x5 get rebooting in many times because of my mistake.
I just recovered by rgn .,

So., you can try ., don't worry.

Hi Aekhong ,

If you can make the TWN Firmware to work with JCV , that will be just great .
Do you mind sharing the idea on how to do this , I want to try it myself as well .
Please share on how this can happen , so i can study more and try it here .

So want to have the street name above the "menu" button .

And another thing , maybe if this work , i'll change the US Firmware 4.0 , so that the touch screen problem will be solved too .

Thank for your good advice will try that out. Good news on JCV. Hope one day can be done on 3790 SG too.
