I have the exact same issue as Rob with nothing plugged in, no lockpick etc.....its probably my aftermarket wheels though, since they get blamed for any other problem i've ever had on a vehicle....I see in your signature that you have Lockpick installed. Is that correct? If so, is it plug and play? You may have to disconnect it in order to perform the update, and like skytrash said, remove anything plugged into the OBDII port. This screen should only last for about 10 minutes.
