06 A4 Eclipse head unit wil not shut off
 

Hey guys, I am having a issue with my Eclipse AVN726e head unit. Out of know where when I shut the car off and take the key out the ignition and open the door the head unit stays on as well as the lighting for the a/c controller. This is the 1st time it has ever done it. In order to shut off the head unit I have to pull the fuse. I have a 06 a4 2.0T. The head unit would always go flush with the dash when shut off now it also stays out in it tilt it is set at when I pull the fuse. If anyone know what the problem is I would greatly appreciate the feedback!

THANKS
