2002 LS. Followed directions on board and got new DVD installed but having a dickens of a time getting the DVD player reseated. I think when I lifted it up to switch disks I may have pulled it forward a bit but not sure. I now can't seem to get it seated so the mount plates are flush with the bolt holes-best seems like about a quarter inch above holes which tells me its not properly back in place. Any expert know if you have to push it to the right or left to get it seated and then slide it one way or the other to align bolt holes/mounting plate? Any help very much appreciated.
