I have a Motorola Razr D3. I was thinking about the possibility of use my cell phone like a FM Transmissor, so i can send a music in FM waves to my Radio in my car. Is it possible? Exist any app for it?
Is it possible?
Only if your device has dedicated FM transmitter hardware or is a software-defined radio device. Statistically speaking, it is very unlikely that any device that you own meets one of those criteria.
