If we have the CD or Radio on we can't hear her say what's next. The Nav volume control setting has no function up or down. I had the car into the dealer for some other items last year...one of which was reprograming the Nav/Sound system with a firmware/software upgrade. Wonder if this caused this problem? Anyone else had this problem?

You can only adjust the NAV volume when it is speaking. When the NAV is talking the radio volume should be automatically muted. Right when the volume is muted turn the volume up.

If its the COMMAND unit i think it is, if u push and hold the ear button underneath the display whilst turning the volume control this can adjust it.
