Thank you for explaining , so in Dylan's resting place the GPS would not of worked due to no wifi?
Actually, it doesn't have a built in GPS chip, but it can be used for maps/navigation etc with the right app. However, since it is only WiFi, you have to be connected to a hot spot for it to work. I don't think there would be any hotspots in that area of Middle Mountain Road, so no... it would likely not be of use at all.

January, 2013 update: The latest version of the iPod Touch, announced last fall, has a lot of great features, but still no GPS chip. Its mapping and location services rely on WiFi positioning only, described below, which can work fairly well in metro regions with ample WiFi hotspots.
..In order for many of the current crop of GPS navigation apps to function, they need always-on, or nearly always-on connectivity. Many pull down map information on-the-fly as you roll down the highway or along the trail. Many navigation and location-aware apps also depend on connectivity to pull down an array of information from search queries and databases. These apps are effectively "broken" without 3G connectivity, which is not available on the iPod Touch.
