Dealership has no clue
I called my dealership and they had no clue. They gave me a 1-800 number to call to Pontiac and they had no idea. They told me to take it to the dealership to diagnose, so if you have taken your G6 to the dealer and got an answer I'd appreciate the post of the answer. Pontiac told me that the message should not appear on the radio. That gave me zero confidence.
