Update: I finally made it to use recent standard official Garmin China maps on my European Garmin GPS units, overcoming the (about) 600 meters shift here in China, which was corrected in the past in the “Venus” modified maps...
it's not a data "correction" file, it's a "shifting" file, every coordinates displayed will be a WRONG data.
