If you live in the midwest, many of the country roads are laid out along section lines -- true North, South, East, or West lines. To determine the correct compass reading, you will need to add the magnetic variation which can be gotten by calling any small airport. If the variation is "west," it should be added to the road's heading to get the correct compass reading. If the variation is "east," then it must be subtracted. For example, if you drive along a road running north and the variation for your area is three degrees east, then the compass should read 357�.

You see I just installed a digital compass in my car; a Ford Escort station wagon. The instructions say to calibrate the compass, you have to press a button, then drive around in a circle twice, stop, then do another 2 circles. I did that and the readings seem accurate. The compass is so-called "V1000 Copilot" How do I know the readings I receive are exactly correct? Of course I know generally which way I'm going (NSEW)and as I turn my car the readout seems to turn accordingly (if I turn 5 degrees left the readout should show that) I realize this may not be the right list to post this question, but if you could refer me to another list or answer this question I would appreciate it. Thank you. Stephen
