Hey everybody just bought my 2004 clk 500 on Monday and was hoping to play music through a aux cord. I noticed one in the glovebox and cannot figure out how to get the music to play. Any help would be greatly appreciated.

 

Press the CDC button on your head unit till it says AUX on the display.

 

On my 2003 S430 (probably different) the AUX input is on the Service button instead.
