GPU or GPS?

Wes,
I see you mentioned a GPU.  What is it?  I'm a pilot and fly by a GPS
regularly but is that what we are talking about?  I can see the advantages
of a zoomed in moving map during a road race course.
My car is getting closer to going out the shop door.  I just picked up on
the Silver State Challange and am quite interested in it.  My brain is
already working on a plan to do the Challange and then to B'Ville the
following week this Sept.  That is if I eeevvveerrrr get the car done.
