Yesterday, I was driving my wife's HyCam (which is set to auto-connect to her cell phone by Bluetooth) home from a restaurant, and my wife and son are ahead of me in his car. My wife called me about something or other and, while we're talking, I pulled up behind them at a red light. Her cell phone then connected up to her car, and I started getting a bizarre feedback of my own voice through the Camry speaker, as well as her voice and some neat Who-style general feedback. Bad enough that I had to hang up right away. Try that one at home! rpm
One time I pulled into the driveway and put the car in park as I had to bring the trash cans in. I disconnected bluetooth and continued my conversation on the phone while moving the trash cans. While walking past my car, it reconnected and I heard my friend's voice coming from the car. Took me a second to realize what happened.
