If the hardware needs to be replaced or modified, well, then, that's a bigger hill to climb than just uploading new improved software with all those "... background checks taking place in the unit to monitor GPS integrity and warnings and loss of certain capabilities that take place if that integrity is lost. ..." (and validating it with FAA), that dlloyd mentioned.
