NAV Voice Directions disabled?
 

So I was driving 2 hours home last night and about halfway through the GPS-NAV stopped giving me turn by turn directions. It would announce the next turn when I pressed the MAP button but wouldnt announce it when I arrived within a mile of the exit. The GPS had full signal and was displaying the map and location properly.

I was using bluetooth audio during the ride and had made a couple calls.

Anyone have any similar problems?
