Rattle from Head Unit
 

Since the day I purchased my camaro the head unit had a slight rattle/clicking in cold temperatures. I know this because i purchased it around november and the temperatures get quite low here. around 30's at night. the rattle was only noticeable when the radio was off and until the car heated up. During summer the rattle/clicking sound was gone, untill now. the noise rarely goes away and its heard when i drive at any speed over 15 mph. if i apply a little pressure to the left side of the display screen it stops. Has anyone had this problem?
