The long term contracts with M2M interfaces for OTA updates are generally low bandwidth. Carriers are willing to sell these long term contracts because it consumes very little of their network capacity. If you started pushing out constant multi-gig map updates across them, then the price to operate their OTA infrastructure (their vendor) would massively increase. That's the point we're they'd probably have you download the update online and usb stick it to your car, assuming they were willing to eat the cost of new maps licenses.
