Interestingly, the iOS app "NavClock" (free) gives a reasonably accurate estimate of height, using GPS. the accuracy is typically 30' or so when you start but gets down to 9' or so after a short while. That should be enough to determine which floor in a multistory garage. I wonder if a Bluetooth connection to the car is able to access the car's GPS (assuming it has one, as mine does). That could be even better, with a bigger antenna.
