I did manage to complete compass calibration which is necessary after installation of the mirror. My compass was showing wrong directions after installation.

1. Find parking lot or a circular drive where you can make 360 degree turn for 2 mins
2. use a small philip screw driver (size PH 0) or something similiar to poke that button at the bottom of the mirror. You will have to press it, hold it for 6 seconds until the compass shows "C".
3. start driving the circle until you have directions shown on the compass. It's better if you have a GPS mounted to confirm the directions
4. Stop the car. press that button again, hold it for 3 secs and you will see a number, press the button until it increases to the number matching your magnetic geographic zone. e.g., Michigan is 9, New York is 11, etc. I have attached the map

Once you entered that number, you are all set.

MISSION ACCOMPLISHED!
