I looked through the owners manual and all I found was something on Setting voice guidance volume? page 352 Also did a search here and found nothing that would help. I have a 2010 III with out the navigation package. Is there a way to increase the volume on the hands free cell phone system. It is fine as long as the car is running under 50 mph. Once I go above that speed wind and tire noise drowns out the voice of the caller. The microphone sensitivity is fine. Thanks.
