Does a bluetooth FM transmitter device exist?

I was just thinking about this the other day. What if there is a device that is small, and sticks into the lighter, and is powered by it. Now, this device, is bluetooth enabled, so that it connects to my phone, and then also transmits the sound of the phone to a fm station, so that I can hear the conversation from the car's speakers.

In other words, I'm driving down the road and I get a phone call. My phone is connected to this device via bluetooth, and so I just press a button on the device and it answers the phone. Then, I push one of the Pre-set FM buttons on the radio to a dead station that my device is transmitting the voice from. Do you think something like this exist?

Could it be that I'm just jealous that my friend's Camry has this phone feature built-in?
