I bought my China city navigator 3 months ago from America.

Yes it is a bit off and slow to keep up compared to back home.

Alot of roads are missing but the main ones are there.I don't think they put alot of effort into Xinjiang.

But I sure use it alot and is a worthwhile investment.

I am told quite a few maps are not accurate up here in Xinjiang some are but you have to find them first.
