If you really need these two subfiles, you can use gmaptool to extract them from the official map then join them to the Venus map.

Thanks for the explanation, so is there's any benefit/advantage if i'm using a garmin GPS unit if those 2 files was included?
Anyway did the '006B082300.bin' confirm corrected the offset for the official NT CHINA 2011.11 map?
