Standard fit audio unit to my W Reg Marea 115ELX... has an "Expert" menu - but no instructions for the expert menu. I downloaded instruction manual that would have been supplied with the car when new, but the "expert" menus are not explained. Is there an "expert" out there who can help?

Never come across that set of menu options before. Put a post in the ICE section, thats' where the audio experts hang out.
