HOW TO: Enable Hidden Audio Menu - Mercedes SL R231 

In this HOW TO video guide, I show you how to enable the hidden audio Fader menu on your Mercedes SL (R231 Generations) COMAND Infotantment system.
With this menu you can set if the sound comes more from the front or the rear. I also explain why this menu was actually removed by Mercedes in the first Place!
