Let me know whether that helps or let me know and I will send more details.

Hi ShuBen,

this helps a lot. Thank you for the fast response!

I've done the first step by porting the "Google China Fix Map Mode" to the Open Source Edition. It solves that problem if the data is correct but the map is distorted. Please download the latest prerelease which I've just uploaded. It tries to correct the map offset for Google Maps for the routing on the map for China. See my screenshots attached which I've made without any manual intervention with the latest prerelease.

Please check it out, play around with Extras/Options/Maps/Fix map for China to see if the heuristics applied work in most of the cases and give feedback.
