Ford Sync uses the inbuilt GPS antenna and your phone (connected via Bluetooth). Ford Sync calls the local emergency number and speak via an offline text-to-speech (Nuance software). The feature can be turned on&#x2F;off in the on-board computer.<p>It&#x27;s definitely better than the new EU regulation where every new car is required to &quot;phone home&quot; the car position every few minutes, so that in the case of an emergency they can locate you. Typical inversion of control for no benefit (for the consumer).
