Thread: Garmin CHINA City Navigator NT 2010.32

China Map so far doesn't require a gma file.
Keep it gmapprom.img und gmapprom.unl.
I had also problems to unlock it when i renamed it to gmapsupp.img

Got it! Finally! Now to load the offset and off to China... Thanks all for the advise

I just tried, no problem. My device is 255W, and it can read the map...But all the maps are in Chinese...Thanks anyways to catymag!
