RAZR M Vehicle Navigation Dock

[kerflumper]

Before I had the Vehicle Navigation Dock, when I turned on navigation and the radio was on, the turn by turn voice went through the car radio. If the radio was off, it played through the phone speaker. Now that I have the dock, if Bluetooth is active, the voice doesn't play at all. I have to turn Bluetooth off in the phone to hear the turn by turn. This isn't optimal because then I can't use the phone over bluetooth. Is there a setting to have the voice always go over the phone speaker?

Edit: Thinking about this some more, I don't remember if I got the dock before or after I updated to JB. Could that be related? It must have been about the same time because now the turn by turn voice never works in or out of the dock if the bluetooth is turned on.
