I have a Droid Bionic and I am learning to use the navigation feature. In a car that has no BlueTooth connection, I can hear the navigation voice pretty well. In my car that is connected to BlueTooth, I can barely hear it. The radio volume goes off and the Droid can be heard through the radio speakers - but just barely. I have tried adjusting the volume on the phone and on the radio, but cannot impact it. How do you increase the volume, please?
