I'm thinking of getting a GPS unit so I'm looking for recommendations.
I'd like to get
something that was good for use on the road and off the road.  I
sometimes go off paved
roads but not really "off road" so it would be nice if whatever I get
has some capacity that's
not "paved streets only".

It will never come out of the car so such issues as size and battery
life are not important.

I have a Mac G4 laptop which I use to drive a couple of cameras (a
backup camera and
an inferred one) which I display on a small monitor.  I'm wondering if
I can use the Mac as
a display for a GPS.

Anyone have any experience they'd like to share?

Thanks,
