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.

I have a very old GPS that has a speed limit of 105 I think....
something in the low 100's ... I know me and a friend exceeded it in his
BMW 3 series. However, pretty much any modern GPS has a speed limit in
the 900 to 1000 mph range. I would think that an in dash GPS very well
may have a remote antenna. Inside the dash could be a much worse
location than on top of the dash. I would bet the antenna is directly
under the plastic dash cover up as high as it can be in the center of
the window or it could be up on the top somewhere. Either way wouldn't
surprise me. Except for the Etrex and tiny units like that, I think all
the bigger Garmin units all have an external antenna jack.

I still think the TV ad is stupid. You can do the same thing with a sub
$100 hand held GPS or a 300 year old sextant (they did have sextants
back in 1706 didn't they?), a $5 watch and some charts.
