What screen do you have?

This may help...

1. While the vehicle is on and running, Then, on the steering wheel, hold down the voice command and green phone buttons for 30 seconds.
2. Let go of the buttons and turn the vehicle off.
3. Once the uConnect display is completely off (black screen) open the driver door.
4. Close the driver door and turn vehicle on and running.

I have not tried this, but maybe worth a shot.
