You need three things to navigate by GPS – 1) A network of satellites broadcasting the current time, 2) a receiver that can triangulate the signal from several satellites to determine current location, and 3) a digital zoomable map to display the current location and calculate routes to other locations. Without downloaded basemaps the only thing you have is your location (and track of previous locations) which is not too useful. Skip down to the i-phone or Android instructions for Waze or Google Maps With pre-loaded (downloaded) base maps and routing information the only thing you lose without cell signal is traffic updates.
