Hey, I was wondering if anyone has any information (schematics, how to's, or other) on how to transmit sound to a car speaker. I saw an advertisement for a cell phone thing to play whatever the person says in your car speaker, and I was wondering if there was any way to do it (preferably wirelessly). Thanks in advance.
 
a small fm transmitter is how they work-- usually there is a clip that hooks onto the cellphone and it will pick up the sound from the earpeice, then transmit it via fm to some pre-tuned station---you can buy a fm transmitter kit from radioshack for about $10
