I'm using an old iPod dock in my car, to have my iphone connected to my audiosystem. It works great.

Now i'm looking for a way, to get my iphone to transfer calls via the ipod dock to my car, so i could use it handsfree in my car.

I'm wanting to use my ipod dock as handsfree system in my car. Listen via radio and talking via the mic on the phone

is that possible?
