OK. I got bumped up to level 2 tier support with my bluetooth problem. They are saying that the iPhone just does not work with Lexus---"it was not built that way". Anyways...the problem that I have is when i make an outgoing call, i never hear the phone ring in the car until someone picks up the line on the other end. But even then after it connects, there is a 3-5 second delay in hearing the other person---by then they usually hang up after saying hello multiple times and not hearing me.
