I used to use one of these: Belkin Auto Kit for iPod sounded better than the straight cable though of course needs power - which I'd routed through to the glove box.

That is good news...I'll order the one off ebay that has both the mini jack and USB charger cables combined.thefmister said:Tested out the FiiO cable today. Much better than a 3.5" jack to jack. The volume is much better and the overall frequency range is better. It's worth the money. I got the gold plated version from dealextreme.com. They are cheap and prompt delivery.

Obviously my iPhone connects on end, on the other I have hard wired in the USB to my stereo (for switched power) an then the 3.5mm jack for audio through the stereo. Cable pops up through the ash tray and into my little dock. Nothing cluttering my dash, out of the way and nice position for sat nav!
