Dude Where’s the Car?

I resonate with the need for the Car Compass because I have been in this situation once. A friend had parked his hired car in the public car park and he forgot which floor it was on. We literally had to go to each floor of the 10 floors to figure out where the car was. Now if we had something like this Car Compass key then it would have guided us to the exact location of the car, using arrows and pointers on it’s display. Sometimes beeps and flashing lights are just not effective enough!
