I followed people with GPS's a couple of times through large Latin American cities. It didn't seem to work very well: we took the least efficient routes, rambled aimlessly in large circles, sometimes didn't arrive at all due to changes, construction, one-way streets etc., and in general got frustrated and started to squabble. I can't say how representative my experience was, but it didn't make me want to run right out and buy one for my bike.
Asking directions is an essential skill. So is hiring taxis to lead you wherever you want to go (which is the only reason I'm here at home, not still circling Panama City with my friend and his GPS). There is no time or place where asking directions is "not possible," and many times when it's less confusing than following directions on your little screen.
Hope that's helpful.
