I am not certain whether my recently acquired 2003 SL500 (base audio system) should have rear speakers. I believe it should, but no sound comes from them and on the COMAND audio settings menu bass, treble and balance adjustments appear but fader (front-to-back balance) does not. I would be interested in forum reader feedback before going the dealership/specialist repair route. With thanks, TS
