All of a sudden, my voice command has gone funny. When I press the steering wheel control for the system, I used to get a voice asking me for a command. Instead, I appear to go directly into the help menu----I hear a beep and the voice nags me to give a help topic. Is there any easy way to get back to normal?

 

Reset the system? Pull off the neg battery cable for 15 minutes? Take it to the dealer?
