Here is my install:

^ The cable I got was: "Long 5ft iPod / iPhone 2-in-1 Audio and Sync Cable. Apple Dock Connector to 3.5mm Audio AUX (Auxiliary) Connector AND USB Charge/sync Connector" I didnt like the cable in the cubbie, so I ended up hiding it underneath. I drilled a couple holes for the aux-in, the usb cable, and the sync cable.

^To get the sync cable through I removed the cig lighter and cut a small notch to the holes for the cables. I used tar tape to fill the holes around the cables.
Thats a "elago Nano EL-Car-001 USB Car Charger for iPhone, iPod, MP3 Players, Digital Cameras, PDAs, Mobile Phones and more (Black)" for the charger, and I dont have any noise issues at all when charging and listening to music.
