Installation instructions, please watch the video on the detail page. (Note: You observe that the direction shown by the white dot is the direction of progress.)
1. First determine the correct direction outside the car, other reference compass should be separated from the ball compass by more than 20 inch.
2. Then find a suitable position in the car avoiding iron and magnetic objects so that the direction of the ball compass is the same as that outside the car.
3. Finally, tear off the double-sided tape to fix the ball compass.
Features: shockproof, waterproof, accurate pointing
Not all positions in the car are suitable for placing a compass, because all compasses cannot resist the interference of magnetic objects. Please find a suitable place in the car to place the compass.
