SLK/R171: 2005 slk 350 Mercedes Comand system and Harman/Kardon LOGIC 7 sound system
Could anyone assist?
The display of my system is blank but my system still works fine. I changed my battery and my audio setting was reset.
Does any one know which knobs I have to use to adjust the treble and bass of the system?
Thanks in anticipation of a favourable response.
