There are AUX cables that have a transmit and recive switch. You can use this to transmit the output of your iPod through AUX to a built in bluetooth receiver in your car or other device.

Just make sure what you choose has the transmitter function as most cheaper ones only have the receiver function (for use in a car stereo for example).
The world would be a better place if the rain washed all the shit away.
