I did have a root option that didn't wipe the phone, but EL29 plugged that exploit. I just fixed the problem with the phone announcing all the time. When I had the phone in the car dock I had turned on driving mode (in voice talk) and it remembered that. Once I turned it of the problem went away. Still want to find a non-destructive root method.
