Another question, is really true I'll lost the ecoroute function? or only my data till today?
Thanks

Your 3750 is also possible to convert to Sg/mal too.

Here is Ecoroute HD

Code:

continue :: Nuvi 3770 Thai is coming soon.
(include :: 3D building map., DEM., Traffic., MP3 player.,TTS., new Ecoroute.,)

Now I think we have a way to go back to US firmware for Nuvi 3790us converted to Sg/My.

It's easy
Make a rgn file to go back US.
-Use RGN_Tool to open original US .gcd
-Override swv to 219
-save to rgn

H/R your unit
Flash with RGN

If boot up normally
Rename folder to original name
H/R again

That's it. !!
