Connected my iPod Classic with Composite cable so I could not only get music, but also view any video downloaded to it. The problem with that is it's quite a bit of cabling added in a car already short on room.
Solution: purchased a relatively small Sony video camera bag and placed the iPod and 75% of the cabling in it and tucked it underneath the driver's seat. Can't see it at all.
The plus to it is if/when I have to drop the car off at the dealers, run it through the car wash, or whatever....all I have to do is unplug it from the console, tuck the rest of the cable into the bag and carry it with me. Has room for my cell phone and whatever else may need to throw in there.
My wife calls it my "man purse" but I immediately flash the 'Sony' side to her to remind her it's a camera bag! If I'm not vacating the car, it stays in the car at all times. Just hate things lying or rolling around in the car.
