The EXACT same thing happened to me tonight! IT clicks when I try to start it, all the electronics flicker and it goes nuts. The radio wouldn't turn off. I noticed the display said changer parked. That is the CD changer locking itself because of a batter disconnect most likely, according to what I've looked up. Tomorrow I'm going to try to disconnect my battery and see if it starts! Please let me know if you found a solution to the problem as I don't have another vehicle and I am supposed to be leaving in a few days!
