Pros Nokia has updated this software and if it was sluggish, that is not the case anymore.
Cons None, but I just use to navigate on a nuclear sub, so what do I know about mapping.
Summary If you own a Nokia phone lately you are well aware that Nokia HERE maps is just a part of the Nokia navigation package. Coupled with the app "City View", Nokia takes you from the map/plan view of the HERE world to a street view, where every business within 360-degrees is readily depicted on your camera screen for you to touch and get directions to. This powerful combination of location information allows the user to never feel lost in the big city.
Nokia, via their NAVTEQ acquisition, has solidified itself in the world mapping arena and offers their technology to a vast array of users including the prominent Garmin GPS systems, who are closely associated with the US Military navigation systems. If that little tidbit isn't enough to convince you that you're getting accurate data, then you're condemned to a perpetual wandering in the streets and asking for directions at gas stations, or you are an Apple user, who was steered to Google Maps.
Pros HERE Maps is the only Mapping software that includes all of NavTeq (World leader in maps) data. It is highly powerful, and has terrific results. It is highly accurate with all 3D modeling, indoor venue maps, and location data.
Cons Author is correct about sometimes slow loading, but overall it has shown great stability.
Summary Overall, it is the best one I have used in recent memory. Highlys recommended.
