hello guys, i was discussing with a friend today about the real usefulness of inbuilt car navigation systems in nigeria. i know they are in great use in the usa, europe, etc where they have clearly defined maps but how useful are they in nigeria? if i buy a car with navigation, will i ever be able to use the navigation feature bearing in mind the extra cost (due to the navigation system)? are they just for fancy or is it worth the extra money paid compared to other cars of its type without navigation?
nigerian car owners with navigation system in their cars, please speak up!
