Portable Bluetooth FM transmitter

We have developed a small portable Bluetooth FM transmitter (BL@ST) with dual microphones for background noise cancellation. German quality.
BL@ST is unique because it's only 20 grams, 2 in by 1 in by 0.5 in and transmits voice, music and GPS voice guidance from your mobile phone/PDA to your car FM stereo wirelessly.
