HELP - Removal of Business CD

[clubba]

So, I'm trying to install the aux input for my wife for Christmas without her finding out (since I also got her an ipod touch for Christmas and I'm hoping to plug it in on our way to relatives' houses as a surprise, but I'm having some difficulty. I'm in the driveway at midnight w/ my headlamp on (neighbors probably think I'm breaking into it) and I've got the MID out - which was easy - I've unscrewed the two hex screws at the base of the Business CD and the sucker will barely budge. It comes out about 1/2" and then feels like it gets hung up on something. The hex screws are spinning freely so they're not the problem. I don't see any of the push tabs on the cage pressed out and preventing it from sliding, but I can't seem to get it to budge past that initial 1/2". Has anyone else had this problem? I've read all of the posts and everyone seems to say it just slides right out. Unfortunately, mine isn't.
