Now South America doesn't have as many roads as Europe, meaning that there are far less intersections and turn-offs. So a GPS isn't as important as for densely populated countries. It is also better sign-posted than eg. Africa. So navigating by maps is fairly easy in South America.
But since I bought my first GPS years ago I wouldn't like to miss it. It doesn't enslave you if you use it in addition to good road maps. Besides that, there are fairly cheap GPS's to be found in Ebay, like the Zumo 550, which is still a very good bargain today.
