Is there an iPhone app that allows one to follow an imported .gpx track, in a car navigation-like way?
The apps I found so far, like Trails, can only display the track on a map. What I am looking for is a "download-and-forget" experience for my bike trips. I want to import a track and just look at my iPhone to tell me in which direction is the next waypoint, or how can I get back on track if I get lost.
