I purchased the car dock and am very happy. I use the auxiliary speaker wire to connect to my cars stereo. I hit speaker on the main menu, then exit to get apps. This works great with music or Sling Box. However, when I receive a call the phone reverts to speaker phone and not the auxiliary stereo. I have even tried placing calls from the main menu and it will not play over my cars speakers. Seems like this would be an expected hands free feature. Any information would be appreciated.
