I have Europe nuvi 3790T and i want to change the software, but the software won´t change after using these SG/my softs. Currently i am using 4.80 software, but i sucks, does not have mp3 and video support
Your 3790 will get rebooting loop for other later versions.
Or get 34xx fw as caty said. :Animated83. Then you can get the newest fw.
SgMy give you mp3 player not vdo player.
CHN 2.20 give you both.
CHN 2.20 is not the lastest fw but it is good enough to try.
Notice. CHN fw will give you no co-ordination function.

Ok i want to try CHN 2.20 but how can i install it? I downloaded the .exe file in post nr. 97, then i plug my 3790T (US) device and tried to install it, but after installation it keeps the same version (SOFTWARE VERSION 4.80)
You must use RGN tool to prepair your FW for flashing.
From .exe file - You can rename it to .rar and then open , or right click then select extract file.
You will get gupdate.gcd inside, this file you need to make a modified firmware.
Your modified firmware will be
- original US boot.bin hwid 1101
- resources.bin from CHN
- fw_all.bin from CHN (overrided hwid to be 1101)
Merge all 3 parts by rgn_tool. Then flash into your 37xx.
Can someone on Chinese or SgMy find and post their chinese keyboard file? Or at least a screenshot of it so I can see that it's working. I switched out to 34xx firmware from 3790US and added chinese maps, but can't input anything cause choosing any of the chinese keyboards just inputs english. Even trying someone else's zh_TW kbd file seems to just input english, so maybe missing some sort of file to make it work?
I thought it would be included in the firmware file, but apparently not.
So looking for zh_TW.kbd or ch_TW.kbd, or whatever else that may be needed to make it work.
Try CHN keyboard and let us know.
If don't work then you have one choice :: convert to 3790CHN (version 2.20) !!
(Thai kb won't work on 37xx-US firmware but works fine on 37xx-Thai firmware.
Yep, no go on the keyboards, as expected.
Guess I'll just have to flash v2.20 and see how that goes.
Thanks for the help guys!
Edit: Seems like 2.20 is working perfectly. Tried 2.30 just in case, but got bootloops, so oh well, back to 2.20.
Is there anything else I should mod to unlock the full potential of a 3790US on 3790 2.20ch? PoI's or whatnot. New to the scene, so everything is really fresh and exciting/nervewracking.
