If your car is under warranty, you should get the firmware upgrade. I just had my car in for maintenance and they updated firmware no issue, though he couldn't tell me exactly what the change log is.

 

Leave the driver's side window open. Do not open the door. Reach through the open window and insert the key. Hey, Presto: the Porsche crest appears. It will stay on the screen a few seconds. Twist the key and it's gone.
