I can't find the auto volume control screen and I have the upgraded sound system. Does anyone know where it is? It's supposed to change the volume on the audio depending on the outside noise level.
It doesn't exist - it was one of the announced features that never actually made it into the car by production time. Dave.
per the manual, it's supposed to kick in based on vehicle speed... about 45-50 mph, not by measuring ambient noise. if it's there at all...
