I purchased the US Central app almost 3 years ago. Did not update as I read all the problems in the reviews. Recently updated my iPhone 4 to iOS 5. I deleted the old app and installed the newest update, which did include the free map updates as promised with my original purchase. I have no extras. The app update has been outstanding in all regards. Based on my experience, it seems Garmin//Navigon may have fixed previous issues. I also recommend delegating the old before installing the new. I have no idea how extras affects the update issue.
