I am new to the Nokia n800 and i see that maps are available for download (western and eastern usa). I have a 16g sdhd card in the slot below the kickstand. But when i try to download directly to the N800 it takes forever and finally says it cannot download. How do I get the maps to download to my N800 or to my sdhd card? Do I download from my pc to the card? If so where do i find the maps to download? Any other tricks to help out???????
