Harbinsteve was looking for maps in NW China.My google maps in my smart phone in Xinjiang was sketchy.My Garmin with City Navigator China NT card had the offset and I tried to fix it but couldn't( I'm no tech head that's for sure)I used the Garmin out in the country and my smart phone in the cities.

China might have good coverage for mobiles but in the countryside in Xinjiang they still have some ways to go.
