560 SEL Radio Code?

I don't know how it happened, but somehow I messed up my radio and it wont work anymore. I heard that you need a code to get it going again and was wondering how I can find the code or if anyone knows the code for this particular car.
Please help me!

Look in the books or the wallet they came in, there should be(if they were kept up with) a credit card sized piece of paper or silver card with the code on it. You can also look in the books themselves, you would be suprised how many times I have found the code wrote in the inside cover or in the back somewhere. If all else fails, take the car or the registration to a MB dealer and they can look the code up in about 1 minute.
