2006 civic, radio not working

my radio recently went out and i dont know what happened. im guessing its a blown fuse. i have a 2006 civic lx and the lights for the radio dont work, however the air conditioner and heater buttons work fine. the only problem is the radio and cd player not working. can someone please tell me whats wrong? thanks
first thing i'd check is fuses if its not a fuse then it may be a shorted wire somewhere and if thats not it then its the radio it self in which case you can get them cheap anyway but i'd check the fuse first
