This is what I have installed with the iPod cable (+$30). The 5140 doesn't have built in bluetooth but the 6140 does. You save ~$100 and you can add BT for a little more than than $100 on the 5140 later. I would recommend the 6140 though if you like the bluetooth feature. I have my Jawbone on my ear all day so I didn't care too much for it.
The headunit itself is great.
