An accessible map navigator for Ipod 5

Hi there. I'm brand new to the I device scene. I just got my Ipod touch 5 3 days ago, so I'm still learning. What I'm looking for might not even exist, but maybe someone here will know if it does. while I'm at home, I want to be able to input an address or location, maybe in another city or even another state, then take a virtual walk, hearing about upcoming streets, as well as points of interest in that location as I pass by them on my virtual walk. Basically, it would be a way to sort of explore an area before I actually go to it in person. Any ideas or suggestions? Thanks in advance.
