I am preparing a 1-week bicycle trip. We can't use high-traffic roads, so I am preparing a quite complex route on small country roads, using Google Maps.
With my phone saddled on my bicycle, is there a GPS app that will "guide" me using the itinerary I crafted? Turn-by-turn would be ideal, but just writing the itinerary as a map overlay would be better than nothing.
Note: My phone is WiFi only so I will need an application that can cache a lot of maps, like AndNav2 or Maverick. Also, I am stuck with Android 1.5
