The Nokia N97 has a built in compass to show you which direction you’re heading. This is especially for pedestrian navigation useful as the map automatically rotates. However, you need to calibrate the compass everytime you open Nokia Maps. According to Nokia’s manual you need to rotate the N97 around all axes in a continuous movement. It does not only take long but also looks strange. Now I’ve found a easy and fast way to calibrate the compass within three seconds.
As you can see in the video, take your N97 with a flick of your wrist in the hand until the indicator changes its colour from red to yellow and finally to green. This usually takes just a couple of seconds. Now you are ready to come from A to B.
