I'm having an extremely difficult time registering my VZW 8830 with my '06 Prius. I have repeatedly registered the phone and the pop up in my phone advises that I am successfully paired with the Prius, but the phone does not show up in the list of available devices when I go to connect it. Our corporate security has locked discoverability but that has never been an issue in the past (this is my second 8830). Why can't I complete adding the phone to my vehicle? Any hints would be welcomed!
