The official Garmin China maps have artificial shift (coordinate deviation) added for national security reasons. Using these maps on normal GPS devices or software will not display your actual location on the map. Instead, you will be a few hundred meters away from your actual location.

Venus is a series of maps derived from the official Garmin China maps but with shifts corrected. Nothing but the coordinates are changed, so all road, POI info, as well as routing, searching capabilities remain intact. Saved waypoints, routes, tracks will have no shift problems. Compatible with topo maps too. These maps can be used on any regular Garmin GPS devices and software as other maps. However, some maps are in Chinese language only and require Chinese support on your device to display and search in Chinese.

Disclaimers of Venus Series Maps:
1. No guarantee or warranty is given. Use at your own risk.
2. The correction may not be perfect. Your feedback is welcome.

For this 2011.40 map:
a. Map is locked.
b. Map ID is 2159.
c. All road and POI names are in Simplified Chinese.
