hi everyone i have a 2012 c300. my radio isnt working. the screen is on, navi works, everything works but the radio. i can change the radio stations but i cant hear anything. i even tried calling someone from my phone via bluetooth and couldn't hear anything as well. i checked fuse #26 (20amp) , fuse #84 (7.5 amp) and fuse #67 (30 amp). all of them are good. any help??

check the fuses its most probably the fuses if everything else works
