[Chris] had made a durable mount in his car for his iPAQ. He uses the iPAQ for directions and playing mp3s. After nearly ripping apart his line-in cable each time he took the iPAQ out of its cradle he chose to create a wireless solution. He chopped up a pair of HP FA303A Bluetooth headphones to extract the receiver portion. The headphone’s band is prone to breaking so it might be possible to find a damaged pair for cheap. The receiver was placed into an old mouse. once the buttons were hooked up to the mouse buttons and a voltage regulator added the unit was ready to start streaming audio directly to the stereo.
