My ASEAN Free GPS Map Project

I have some question and hope somebody know and share.
I have an Oregon 300 US version, so it can not display font in menus and maps in eg Chinese maps. So is there a possibility to change it to display font in menus and maps in other languages (Chinese, Japanese, Thai...) and have a right keyboard for searching, editing in that language easily only by adding some new font files in Garmin/ExtData (change name if necessary?) and one translated, modified file .gtt in Garmin/Text? Or the firmware must be changed in someway?

I have seen in Garmin/ExtData some (font) files: 006-D0962-05.bin and 006-D0952-06.bin in the device. I guess these are fonts converted from TrueType .ttf, but which format is .bin? Is there any tool to convert .ttf to .bin?

In *.gtt from other Garmin devices Nüvi 3* or similar there are 2 tags <upperkbrd>, <lowerkbrd> that allow to change the keyboard. Could that be applied to Oregon as well?

Use Garmin WebUpdater after firmware update, there are text & voice update menu. Select what u need don't update all.

Thank you for quick reply. At the moment I still see no other option available except the file gupdate.gcd

This was done by a team at http://www.smart-mobile.come
This will require a lot of effort and understanding.

That is exactly the right thing! But I could not understand Thai . Could someone understand and explain here again?

1. insert font into 006-D0962-05.bin and/or 006-D0952-06.bin. How to do? Easy !
just XOR the file with the first byte of that file then rename it to *.TTF. After finished, just XOR it back, and rename it back to *.BIN

2. Make translation to the file .GTT

3. Modify code of the firmware (GUPDATE.GCD)
Before you can do modify firmware, you need to unpack GUPDATE.GCD. Then, do modify firmware. And pack it back.

4. Upgrade firmware

Remark : to deal with GUPDATE.GCD file is not an easy job.

After checking the *.gtt, i could not understand how the device knows which location to change the keyboard? Only with codepage 65001? Or it must understand human languages?:)

It is really difficult to modify the *.gcd file. I only know some tools for unpack, merge the gcd file from here: http://e-trex.info/archives/2008091737 and updater.exe from Garmin.

Little_frog, you are a real hacker and a recognized Garmin-expert!

I don't know if Garmin could combine several keyboard types in one firmware (maybe only one general keyboard?): e.g Chinese with 2 level input, Vietnamese with several diacritics in one character...

Hi กบน้อย(Little frog),

I'm also want my Oregon to be multi language (Thai, Chinese & etc).
How to do it by easy way. I'm not IT expert.
