Is anyone else experiencing the problem below? This just started with ICS and the new navigation voice. When listening to music (Pandora, Rhapsody, etc.) and using navigation, the volume of the navigation is extremely quite. When plugged into my car stereo, I can barely hear the turn by turn directions over the music (The music is a great deal louder). This is making it impossible to listen to music and use navigation at the same time, as you have to turn the car radio volume all the way up to hear the turn by turn voice guidance.
