@bunanson.
Thanks for all your updates man. really helpful.
though am having issues with mine.
I have windows 7 ultimate running and i have an updated Maemo running on my N900 as well as an updated "OVI SUITE".
I went to the maps tab, clicked on Africa, then NIGERIA and download (20MB) after it completes successfully, i go to my N900 > menu > location and navigation > maps. but it still asks me for internet connection. Am i doing something wrong? Am about following the instructions here and was wondering if am missing something...
