If you have the Ipad then I wouldn't bother with anything else. If I understand you correctly, you just want some type of music storage device that you can play music in your car with. While the Ipad is a bit bulky for just that, it would be fine for what you want to do. The Ipod touch (same size as an iphone) is basically a smaller version of the ipad. I would load my music on the ipad and just play it through your aux plug on the Accord.
