I didn't realize it at the time, but Google maps do not match GPS orientation in China - it seems to be 50-200 meters off. The satellite images are spot on, as are Open Streetmaps. I have heard that the Garmin maps are off as well. I was originally trying to use downloaded Google maps with my Droid, but after a confusing day, downloaded Open Streetmaps instead. They aren't as detailed, but will do a good job of telling you where you are.
