I leave my bypass switch on sometimes and GPS still works. If I go through a tunnel, it gets lost though. With VSS enabled, it can figure out where I am within the tunnel without the GPS signal.
I think there may be different versions of our nav system though because others have mentioned that their GPS goes wonky without VSS and others have said disabling VSS still doesn't allow them control of head unit or ability to show movies since it still detects movement based on GPS.
