Need advice. As above, my car fitted with the bog standard, factory fitted head unit, not the Bose unit. All standard factory speaker units in doors plus tweeter/squawkers.
The head unit equaliser settings not obtainable, ie: simply not showing in the display, therefore unable to engage. Sound is presently awful, tinny, hollow sounding.
Swapped the unit from my car into an identical 156, and the settings visible on the display and worked. Unit from other Alfa when fitted to my 156, same problem, still not showing nor available. Could it be wiring loom or ECU settings?? HELP please ... all thoughts welcome to explain this enigma if anyone has had same problems or knows how to solve it! Thanks (hopefully) in advance.
