Great woops! I wish I would have seen this before I installed Vlingo.
Now even though I un-installed it, I still can't get my phone to work right with my car.
This is from their support site.
"Bluetooth in-vehicle installation not working
Why doesn't Vlingo work with my Bluetooth in-vehicle installation?
Vlingo is adding hands free features with each release. Version 3.0 is the first to support a variety of Bluetooth headsets. However, Vlingo does not yet support other types of Bluetooth devices such as car-mounted installations.
To prevent Vlingo from trying to communicate with your in-car Bluetooth system, turn off Bluetooth support in Vlingo Options.
To use Vlingo with your Bluetooth headset, continue to press the side key rather than the button on the headset."
