I had this unit installed at my local Best Buy, they did not install the audio jacks for the ipod. I took out the unit not disconnecting anything, but just to hook up the ipod adapter. We went on a short trip and I used the navi and noticed that once it got to 2:00 and 1:00 marks the songs went out for a second. I started to realize, "hey, isn't there a voice that's on these?" I messed around with it some more and when I make a call the receiving end can hear me, but I can't hear the voice of the caller nor the dial when I'm calling someone. So there's ipod, fm, dvd working fine, but no navi voice or phone sound on my end. Anyone had this issue?
