Alex..There is an off/on voice icon in Google Navigation. I always make sure it is on. Most of the time I begin the navigation sequence before I start my car. I have voice directions. Once Bluetooth syncs, the voice navigation directions cease. However, I have not found a button to use Bluetooth audio. I will be getting a new Droid RAZR HD within the week and will set up Bluetooth and try the navigation to see what happens. I think it is something in the MyLink software.
