Thread: China maps offset - how to correct it

Hi, new to this group, and I realize this thread is old, but has someone tried this offset file in China? Does it work? I'm traveling to China more and more for work, and I'm contemplating getting a gps device just address this gps offset there. In most trips I've done, Google maps on my phone seems to work great, but last year this offset appeared when I arrived in Shanghai, even though it had worked fine the day before in Beijing.

Hi, same for me I can't get it to work, the offset is still there. I bought the China map from the Garmin website in the USA, a waste of over $100. How come they can sell a useless map? I had an older version bought in Shanghai and that works perfect. Just wanted an updated satnav and map. Not a warning anywhere that all the maps are there but your car location is 0.5 mile away from where you actually are.

Contact Garmin US to claim the map is not fit for purpose and ask for a refund. They may have an 'out' if your device isn't in the compatible supported devices list however. If you have a China localized device meant for the domestic China market it may explain why the older Chinese-purchased map worked.

If you have a device localized other than for China, search google for "China Venus shift-corrected Garmin map by syzygy" however I can't say if there's any recent ones around. Indeed the map you bought in Shanghai may be a 'Venus' version because an official shifted map simply won't work properly in any Western or other Asian devices, except for some only if the BIN file works. Shifted maps work perfectly in devices sold in and localized for China. Venus is unofficial mapping which has the shift corrected to show the location correctly.

Unfortunately, the latest version of the Venus is City Navigator China NT 2016.40, syzygy stopped at this. See more at sosaw.com ...
