My youngest son and I were returning from a basketball game Tuesday evening when I began to notice a strange sound coming from the back of the car. It was a repetitive noise which would stop occasionally and then continue. It made me think something was knocking against the underside of the car. With only 1100 miles on my 2012 Volvo XC70 demo, I didn’t thing anything could be wrong so soon. I turned my head to get a better listen when it hit me. New Volvos have Bluetooth with Audio Streaming. You can stream internet radio, mp3s, or any other sounds from your Bluetooth device. The sound I heard was Trenton playing a game on my Windows Phone. The car had picked up the sound effects and was playing them over the car’s speaker system!
