http://mappistapp.com/ Mappist lets you explore maps on your TV. It offers street, aerial and topo maps (aerial and topo only have decent coverage in the US, for now - the others are good worldwide) and you can search place names to find them on the map (play/pause). You can use a game controller to scroll and zoom. Currently it supports OpenStreetMap, OpenAerial, OpenCycleMap, US Geological Survey Topo, Imagery, and Imagery/Topo. Future updates will allow user configurable map sources for more mapping options. Search "mappist" (or just "map" or "nav") in the App Store. Let me know what you think.
