Looking for this cord?

Can anyone tell me where I can locate the white cord that is plugged into the fm transmitter? This would work perfect for me as I have a line-in, but would also like to be able to charge my ipod at the same time (without having two seperate wires). if anyone can find it, or knows where to get something like it, let me know!



Thanks, ste

edit - or the whole thing would work also...
