Folks,
A compass is a compass. They are not made for a particular part of the world. They ALL point to the magnetic North. You must make a calculation depending on where you are in the world to find true North from there. Look on your map to find the local deviation from true to magnetic and go from there. Some other fancy compasses may do this automatically, but they are really just looking at a map they have programed into them.
If you are planning to attach one to your bike make sure you get one that is made for automotive use. These compasses will allow you to make corrections based on the metal and magnetic activity caused by your "running" vehicle.
