Until we start seeing stereo receivers with built in Bluetooth recievers, this looks like a great way to get your PDA, Smartphone, or any other device capable of streaming Bluetooth music to your cars speakers wirelessly. I think this is something that many folks that don't use a dedicated music player will totally dig. Let's just hope the tranmitted signal is strong enough to reach rear antennas.

Bluetooth Hands-Free Transmitter provides a live full duplex communication solution using Bluetooth technology through FM transmission to your FM car radio and allows you to speak to callers through a built-in DSP microphone (it turns your car stereo to Giant Bluetooth Headset). This is accomplished without the use of external wires and without the hassle or expense of custom installation. The device is pairable with any phone equipped with Bluetooth functionality or a connection to a Bluetooth adaptor. Device is AD2P compatible and will transfer MP3 Music using AD2P.
