I listen to my ipod through the cd charger input of my car stereo but have to plug a jack lead into the headphone socket. Having looked at a couple of threads it appears that the headphone signal is not as good as the line-out on the dock. Does anybody know whether you can get a cable that will provide a line-out signal from an ipod without having to use the dock. i.e. I want a cable with the bespoke ipod plug on one end and a 3.5mm jack plug (or preferably socket) on the other.
