Outstanding. I already have the app but not sure I'll ever use it. Easier just to say the name in the phone and done, google nav does excellent voice guidance. I wouldn't have got the nav in the car at all if it hadn't been bundled but in hindsight I think that might have been a mistake were it a possibility because the idrive integration makes it quite a bit easier to fiddle all the settings for the assorted crap.
