I just received my ROAV Viva a couple days ago. Most everything seems ok, however I am having a big problem within the "World Detective" app and the "Word of the Day Quiz" (and I assume any other "interactive" app). When I am asked to give an answer posed to me by the app, the ROAV Viva seems to not hear my response (it might occasionally, but rarely). As a result the game just stops. Very annoying! I enjoy these interactive games especially when having to be out driving by myself. It seems to hear reasonably well at other times, but not when using these interactive apps.
