Well the date/lat/long stuff would seem to be the easy part. Any sort of routing would open up an entire new can of worms as the other navigation/GPS threads in the Projects board have suggested. There are all sorts of different map formats, and doing routing based on this data doesn't seem to be an easy programming task.. I doubt any of us have expertise in this, and I don't know of any freely available software for parsing out these vector formats for routing purposes, but then again I haven't looked very closely yet.

But the journey of a thousand miles begins with a single step, so lat/long would be a nice first goal.
