I have my iPod connected via a Belkin "Auto Kit for iPod" (BestBuy for around $30). This eliminates any "noise".

It plugs into the 12v outlet. It has it's own aux input. I plugged one end of the "mini to mini" gold plated cable I bought (at Walmart for about $4) into the aux input on the car, and the other end into the aux input on the Belkin.

The Belkin then has a cable that plugs into the bottom of the iPod, (dock connector) and allows the iPod to charge and play thru the aux on the car. This also allows the iPod to reach into the center of the car... with only one wire attached directly to the iPod...if a passenger wants to change songs.

It will pause the iPod when the car is shut off, and all that is needed is to push play when I start up the car again.

nice!
