I can only guess. Ovi loads everything on initialization, POI, landmark etc, altogether a whopping 1.9 G, if you have the whole USA onboard. While google loads only the portion of the map upon request, and then download whatever you want to do with it bit by bit. Your question is similar to loading and initialize a program vs download a webpage, I think they are different ballgames.........anybody wants to fill this up? TIA,
