I have a Nexus One with the latest version of Google Maps that has offline caching. It's my understanding that it will download maps of frequently visited areas for offline use. However, I'm going to be traveling to London and would find having the maps cached for offline use extremely useful since I am not going to be using data roaming. Is there a way to have Google Maps download the London maps before I leave on my home WiFi network, so they're available for me when I arrive in London? I don't need navigation capabilities, just the maps. Thanks
