GarminCCN660 Great Wall GPS map
I've been spending quite some time searching for a decent GPS map of China. So far the best one I have found is the World map of Garmin. But as expected, this map has a poor resolution.
Hopefully it is only a matter of time before there will be a better alternative on the market. If anyone comes over a better GPS map of China, I would appreciate it if you could let us know.
I found this nice piece of software to exchange data between the GPS and the computer. Maybe others will find it useful as well.
