For several years now there are two Garmin maps available in both English and CHS. One has the offset still and the other does not. It is well documented on various relevant GPS related forums. Each of the two map versions (not relative to language here in this context) are referred to as 'Venus' and 'Official' map versions. Official Garmin China maps have an artificial offset or shift (co-ordinate deviation) added for supposed national security reasons. Using these maps on a GPS device or software will not display the actual location on the map. Instead, the given location will be anything from 1 to 500 meters away from the actual location.

Venus is a series of maps derived from the official Garmin China maps but with the offsets or shifts corrected. Nothing but the co-ordinates are changed, so all road, POI info, as well as routing, searching capabilities remain intact. Any saved way points, routes, or tracks will have no shift problems. Compatible with TOPO maps too. These maps can be used on any regular Garmin GPS device and software as can other maps. However, some maps are in Chinese (CHS or CHT) language only and require Chinese support on the device to display and search in Chinese (CHS or CHT).
