My understanding is that Google Maps does not provide a NZ map to be downloaded onto the handset. The handset uses 3G to establish the position (which might account only a couple of KB) then the GPS chip kicks in. However, the phone has to display the map.
1. So this real time downloading of map, how much does it use per hour of driving? Ie., if one is driving from Wellington to Auckland and the memory cache is clear.
2. In areas that does not have cellphone coverage or 3G coverage, does it just display a single colour blank map and the map automatically resumes displaying when it is in coverage?
