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.


Several thoughts:

1 - The display was probably simulated.

2 - HOWEVER! One doesn't need an antenna jack with a re-radiating antenna:

I have one, and it works great. If the display wasn't simulated, the
Vortech could have been re-radiated the GPS signal inside the airplane,
making the car's GPS work correctly.


3 - But then again, EVERY dash mounted OEM auto navigation system
actually does have an antenna jack, it's wired to the _vehicle's_
external GPS antenna. G
