Did you use a dash kit? Im assuming you did. Just grab ahold of it and yank that thing out of there. When you say it is stuck, are you using the keys that should have come with the radio to remove it? If you are afraid of breaking something just go to a stereo shop and see if someone can get it loose for you. If you came to my shop i would do it for free, just cause it should only take a few seconds. However most shops will want you to pay.
