Whaleboy,
Back to our GPS software discussion. Just FYI if you still interested in MS MapPoint. I recently found AGPS (Advance GPS) add-in component for Microsoft MapPont 2001/2002 and this particular component makes MapPoint to be a real navigation software with all navi features and GPS capabilities as DeLorme and Co-Pilot has (I think so, but I cannot say that I'm 100% sure). I did not have a chance to test it, but based on features description and tech. documentation I can assume so. Will probably test it this weekend to see how it works.

You can download most recent version from TechGT dedicated web site. Only all further upgrades and tech. support will require official registration with a nominal fee ~ $10

PS: I think that component is also comparable with Microsoft Streets and Trips.
