This may be a dumb question, but how well do GPS's work in foreign countries? Is there a limitation to using them over there? I have an older Garmin GPS and am planning on taking it on a trip to China. Since I'll be in one of the small, non touristy areas where language is definitely going to be a problem, I just wanted it to be able to get back to a known location after a day of exploring.
I did find this article after a quick search, but I'm not sure if the information is still current
Anyone have any comments?
