This is an artificial limit that manufacturers design into their GPS units
to force you to pay a premium for a device that can be used in an aircraft.

I have no doubt that they did drive a car into a C130. I
just question whether they went to the trouble to have the
GPS in the car actually work while in the cargo bay.

As for the speed limit on the GPS, I presume it is the rate
at which the computer can identify new positions and the CPU
can calculate, it is just a cheap $125 hand held.
