We find GPS to be very accurate in Mexico - Garmin anyway - with current updates.
The biggest error with GPS we have found is to allow it to plan your route and then follow it blindly. You must plan to route and work at finding the best route. Once you do that you can follow the route with your GPS. Most "paper maps" only major roads while GPS can show you every street in town even in small villages - though not all villages even show up on some maps.
GPS is based on the data companies such as Garmin buy and then put into their data base. If the data is not available they will not have it. In most cases we find they have more than we would expect. But again - the trick is to work at planning the route using the GPS and looking at where it is taking you - you can get other advice about your route from those who have gone before - then add as many "waypoints" as needed to force the route to go the way you want. That is how we do it.
Maps can be a couple to a few years behind road builders. Mexico or whatever country has to provide the data - that would be point by point Lat Lon along the roads to show an accurate depiction of the road so your GPS always shows you as being on the road. I do not know about going beyond Mexico but in most of North America our GPS is dead on accurate with less than 50 feet or so.
