There's a "Pos Mode" in the Menu, but it sucks, at least I found it unusable, especially in conjunction with a real GPS. One of the changes I plan on doing (listed on my page) is to modify the directional pad to allow simple panning of the map, which would prove very useful in an Offline mode - you could use it as a simple map reader. Right now, however, using GPSDrive as a map reader is darn near impossible on the Nokia 770.
