alright so my friend and i were putting in my head unit yesterday (pioneer premier deh-p8mp) and when he was holding it and i turned the car off, his hand got in the way of when it was sliding open, so it wouldn't open all the way. now when i hit eject, it slides open a tiny bit, but just keeps playing the cd player. it does the same thing when i turn off the car and it's supposed to slide open. just comes down a little bit and stops. anyone else have/had this problem?
