  Wayfinder needs gprs coverage when calculating  a route. It might work 
without gprs coverage  if users stays on the route and do not  need to 
look the map. Not tested, here it is hard to find place without gprs 
coverage but with gps coverage.

  Wayfinder stores map data in centralized server and the server also 
calculates  the routes. After calculation route is loaded back to the 
phone. If user wants to see map  suitable amount of map data is also 
loaded to the phone. Wayfinder cannot directly access other map formats 
but user can download some city maps from Wayfinder  site to reduce gprs 
traffic. Wayfinder has also  map cache to reduce traffic.
