No sound
i checked for the amp and there is not one. BUT I have also checked the other [2 ] 2005 C230k i own and also NO AMP but they DO have sound (no amp in all three cars).
please help. What can I do?
When did the sound stop? All of a sudden?
If the unit is dead, no lights then look for the fuse!
If the unit lights up but still no sound under any conditions, it is something major in common with all 4 speakers. Either the power amp IC or something else internally.. Very difficult to fix unless you have electronics experience.
