Hi Dylan!
Welkom on the forums

I have the routemaps (not gps) ready for the (planned) route between Turkey to Kashgar. The Tibet google earth/maps route is finished now and goes from Kashgar to Lijang.
I will put them online on our website this weekend so everybody can use them in planning their trip.
During the tour I'll have a gps with me for tracking the whole route...
For the most recent info and possible routes have a look at Carl's site, he started in Austria:
