How do I fix my radio?

I have a 98 Mercedes ML320 and the Bose radio that came standard with it seemed to have sopped working after I had changed the alternator and replaced the battery. I checked the fuses under the hood and it still doesn't work. What do you guys think i should do?

How do I put my code back in even if the darn thing doesn't power on? I tried pushing all the buttons, but no lights come on and there isn't anything on the screen.
