On other hand, my coordinate was quite different during the test. On newer maps, my coordinate was about 500m SE from the actual one, according to Google Earth.

So the conclusion is: From version 760 on, the former offset correction file, namely the 6kiB GMAPPROM.IMG file, is included in the map and will change the coordinate instead of change position showed on the map. Anyone with a problem displaying those maps should consider upgrading their software to support the integrated file.

And Garmin will certainly continue making offset, as long as it stays in business in China. The government believes the coordinate is "national security" issue and requires all map publishers make offset, thought anyone now can just download Google Earth and have the exact coordinate.

Hi lh128,

When I use the older map (Map 650) when I visited China last June, I added a file "006B082300.bin" to the /GARMIN directory (i.e., the same directory as the gmapsupp.img). This "006B082300.bin" file corrected the offset (position and coordinate). Have you heard of such a file? Do you know if it work for Map 760 and 2010.21. You can get this file from dropbox [Only registered and activated users can see links. ] if you need it for testing.

Thanks.

Last week I download China City Navigator NT 2010.21(CH) into my Garmin 205 and traveled to Beijing, obviously the coordinate was about 500m out from the actual one, and cannot use for navigation at all.

As I said before, there is no way you can get both correct position and coordinate at the same time, using an official Chinese map, because of the government regulation.
The so called "offset correction file", ie. 006B082300.bin / GMAPPROM.IMG, is actually a coordinate offset file. By shifting the coordinate to the opposite direction, together with the offset map, Garmin will find the correct location for you. Now this file is part of the big IMG so you can get rid of the file and make things much easier. So basically, you no longer need the file if you use version 760 or 2010.21. But since you already have it, you may also keep it for insurance, because at least for me, keeping the stand-alone correction file with a integrated map won't shift my coordinate twice.

And it seems, at least what I saw on a Taiwan website, that the 006B082300.bin file only works for Nuvi / some Oregon models. So sorry I'm not able to test that for you. If you're using Mobile XT as I am, I can say for sure that you don't have to put the "correction file" into Garmin folder anymore.

Hope it clears your doubt.

according to Garmin site, these one should have english too. So far no one shared it tho.
So the early english version should be "Garmin City Navigator China v7.5 QSI ENG with Offsets Corrected"
of course waiting for the 2010.21 to come!

Hmmm... in this case, I will bring along two SD cards, one with the offset correction file and one without the offset correction file. In this case, I can be absolutely sure that at least one of them will work ... hahaha! By the way, I will be deleting the offset correction file from my drop box soon. So if anyone need it please grab it within the next few days.
