i need to have a connection to the car, uncle tom cobbley (sorry tom) mentioned the Griffin Technology: AutoPilot - Charge/control/play your iPod or iPhone through your car's AUX-in port

what i want to know is do you use the 3.5mm jack lead as well as the 32pin connection that gives you power from the ciggy lighter socket? or is the 32 pin connection thru the radio?
