May I know how frequent Live map do update and how do I know when was the actual update of live map? Attached the picture I took from live map (last update 4.30.2013). I found that the live map was not changed accordingly as last update 4.3.2013, but the navigation was correct as shown in bottom of picture. This problem will confuse the user who would like to use live map for checking the navigation route.

Thank for any help.
