After seeing this commercial and viewing the documentary on the Land
Rover website, I still can't figure out how they got the GPS unit in
the truck to work while inside the plane. The doc. showed a guy
sticking something to the plane's windows that might be an antenna, but
I doubt a dash-mounted GPS in a car would have an external antenna
input? Also they said the speed of the plane might be an issue for the
GPS. Can't figure that part out either.
