The advantage of a GPS to me would be the ability to track the route while watching another channel or listening to music.
My experience with using a GPS on a plane is that it isn't the speed but the lack of open field of view that usually prevents the signal from acquiring. You pretty much have to be in a window seat and hold the device at an angle so that it is mostly pointing up but also out the window to get a signal.
