Geofencing to Unlock Vehicle Functions Detailed in New Apple Patent Application - Mac Rumors "According to the 15-claim application, which specifically describes "Accessory control with geo-fencing", the accessory (which may or may not be built-in to the car itself) would transmit a signal to a linked mobile device, allowing the device to monitor the location of a vehicle. When the mobile device (and the user) are close enough to the car, the mobile device would transmit a second signal to the accessory within the car, allowing it to trigger functions like door unlocking, defrosting, heating, trunk opening, seat warming, and more."
I could recall a few times I lost my car in the parking lot. Having a application that will give me step by step directions to find my car can be great.
