This is my third droid phone and I have never had problems with using the bluetooth in my car until now. Ok so when I get into my car it connects to the bluetooth without any problems. When I receive a call, the echo in my car is unbearable. In addition to that, the bluetooth light on the phones goes off and the speaker phone buttons comes on, by it self. The call can then be heard through both the phone and my car. I will then switch the bluetooth back on and minutes later,it'll switch back. Either way the person can not hear me very well and the echo in my car continues. I am using smart actions, but it doesn't help. I have a infiniti g35. Any suggestions would be appreciated.
