Hello. Going to Japan next month. The Ovi Maps for Japan is a bit on the crappy side (something like a 6MB file for the entire country; so very little map detail). I have Google Maps on my phone, but international roaming data charges are expensive as hell (though I suppose I could load up Google Maps when/if I find a free open Wi-Fi network). Looking for some maps that I can download to my phone and use the integrated GPS-only with them. Anybody have a good alternative for me?
Thanks in advance.
