BlueTooth is the best solution:
use an old bluetooth headset, unmount it pick the two speaker wires, connect them to the aux (R/L: RCA or Jack). You can even put the headset inside your car sterio. Don't forget the power supply.
And put the MIC out to be able to make phone calls.
Enable the auto connect option on your BB, It's done and have full wireless fan.
That's my home made kit for my car.
