the map loader works under Windows XP, does not work with 7 (not sure about vista), i have tried both of them. And also, n900 user needs to use mass storage mode.
i have just bought a n900, my question is, can i only use ovimap when i have 3G (data) or wifi ? if not, what are the steps to set it up. if so, what other free GPS application can i use. thanks
