Any receiver can potentially transmit, or re-transmit a signal.
Modern airliners are heavily dependent on properly functioning electronics, especially at takeoff.
When it comes to the safety of 100+ passengers, a lot of airlines would rather annoy the occasional GPS user.
The Capitan of the aircraft has the final say on what goes on his flight, much as the Capitan of a sailing ship. I think they can also perform marriages, if the flight is long enough! ;-)

Does anyone have an idea of the logic behind banning use of GPS units in flight?

I can see why devices which emit a signal, like a cell phone, could be suspected of possibly interfering with the plane's electronics. But it seems like a GPS would be more along the lines of an MP3 player or something. Just wondering if I'm missing the point here...
