Most GPS units have an available external antenna. You'd probably want
to do that, or make sure the GPS has a clear view out the windshield
(not always possible). A cigarette lighter adapter would be worthwhile
as well.
Keep in mind that while GPS units have gotten MUCH more accurate since
the US Gummint unlocked the good codes, they still don't get much closer
than 3-4 meters. Will that be accurate enough?
