This is my first post so please be kind. I just had a Z3 installed in a 2006 Chrysler 300c. I receive no sound from the navigation woman or bluetooth. Other people can hear me if I make a call, but I have no sound coming from the speakers. Also, if music is playing it will mute for or a call or nav instructions. I'm going back to my installer next week & I'm hoping I can get some info to help him out. Thank you in advance. Great site!
