IMHO, I would try to keep the IPOD in the tankbang. Would offer more protection from the elements. In reality, it would be kind of a tricky manuver to focus on the IPOD screen and to safely keep your eye on the road at the same time. Just a thought and opinion. I have mine in a Contours hard case, but am opting to keep it in the tankbag for the reasons stated.
