How to convert 3790us to 3790 Sg/My

**kevindd992002** · 28th June 2011, 02:10 PM

So it's always safe to always use RGN files in flashing?

I have 3790 us with SG/MY 2.30. And Full Screen Junction View is shown no matter of what option is selected(Half Screen option is ignored). Do you also have same trouble?

Does it display Thai JCV as well?

Thai JCV is displayed by Thai firmware only.

I have successfully updated the firmware with boot.bin from US 3.60 + fw_all and fw_resource from CHN 2.20. Unfortunately, there is a alarm screen, which cannot be dismiss, before the setting screen. The computer cannot access the mass storage mode when I tried to connect the gps to computer through usb cable. Anyone has suggestion for me for this situation. Thanks for your help.

Hi, I've been trying to convert US 3760T to SG 3790.
All steps have been followed, however nothing changed

When using updater.exe + modified .rgn, the progress bar straightaway shows 100% for a few seconds then the error info popping up in windows. Nothing changed in my nuvi

Tried another method to directly replace GUPDATE.GCD with the modified one in .System then restart the nuvi, also noting changed

Any solutions?
