I had this thought. Do any of the “driving directions” places, like the
AA or MSN MapPoint or Multimap
allow you to input GPS waypoints?
Alternatively, is there anything on the net which translates
GPS waypoints into postcodes? If there is,
then if you can pipe a net connection into your car somehow (GPRS is the
obvious solution here) then you’ve got satellite navigation, because you
just keep fishing your current location out of
GPS and then query the site for how to get to
where you’re going.
Of course, it’d cost a fortune in connectivity bills, and you’d be
better off just buying a real satnav system for four hundred quid or so,
but that’s not the point.

and articles. You can take a look at some projects I've worked on and
some of my writing. If you'd like to talk about your upcoming project,
