Thread: Honda Goldwing 2006-2008 Navi GPS Firmware Update Versions 4.60 & 4.70

It looks like RGN_Tool can't help us, as it doesn't detect rgn11.bin region number properly and we can't set it manually.
But we can use one of my private utilities, called gfw.exe.
In order to make a GCD file with the dumped American voice inside do the following:

1. Create a folder somewhere and call it BUILD.
2. Copy any original GCD file that suits your device to the BUILD folder and call it gupdate-org.gcd. Copy gfw.exe, gfwdump.exe, and gfwdump.bin to the BUILD folder.
3. Open cmd.exe and make sure the current folder is BUILD.
4. Run the following command line: gfw.exe unpack gupdate-gcd.gcd. This command will unpack the GCD file and produce the following files: 0008--0109-01CC.bin, 02BD--0109-01CC.bin, 0515--0109-01CC.bin.
   Those files are named as follows: section number in GCD--HWID in GCD-version in GCD.bin, where all numbers are written in HEX.
   Section 0008 is boot.bin. Section 02BD is fw_all.bin. Section 0515 contains some small map.
5. Delete 02BD--0109-01CC.bin and 0515--0109-01CC.bin, as you need only 0008--0109-01CC.bin (boot.bin) in this case.
6. Run gfwdump dump gfwdump.bin . in order to extract the dumped regions.
7. Rename rgn11.bin to 0511--0109-01CC.bin.
   Why exactly this name? It's easy. HWID and version should be the same as boot.bin's ones. And 0x5XY is a generic GCD section number for any region 0xXY, except a few regions like 0x0C (boot.bin) and 0x0E (fw_all.bin) which have their specific GCD section numbers.
8. Run gfw.exe bldfldr . . . in order to pack those .BIN files to GCD and RGN file. gupdate.gcd will be created, which is what you wanted.
