Maybe the following link will help in getting the clock panel off. You'll have to create an account with scoobymods, but it's totally worth it.

That thread is not totally oriented towards removing the clock panel, but it contains some good info. I would suggest pulling the fascia vent to get it out. It allows you to get at it from underneath rather than prying from the top, although a little bit of prying often is necessary.
