2001 Galant CD Player Issues...HELP!

So, my car battery died a few hours back and I jumpstarted it. When I got back into the car, the CD Player Displayed : CODE. I fiddled around with it and somehow by my luck locked myself out of it by guessing the CODE wrong 3 times...Now it says "OFF" and won't change. Anyone know how to reset this, so I may enter my CODE (and what is my CODE, anyways? :banghead: )

Please Help!

If you don't have the code you have to take the radio to the dealer and give them the radio and ask them for the code, if they have to remove it from your car they will charge you around seventy to a hundred dollars. They don't suppose to charge you for the code. Good Luck.
