I don't really like Nokia Drive. It's okay, but if they want to be a real player in the navigation category, they need to get Drive better integrated with the OS. As it stands, Drive's voice directions don't pause music playback, which is a huge oversight, in my opinion, as I always have my phone connected to my car stereo for music playback and can't hear Drive's directions. Further, they need to improve search and allow users to choose contacts with addresses as destinations. That there's no such integration boggles my brain.
I prefer Bing maps' navigation, even though I have to tap the screen to hear the voice directions.
