The azimuth of AMC5 = 180 +/- the magnetic deviation.
You can find the manegtic deviation for your location at:

Actually it is the variation and "not" the deviation. By definition variation is the difference between true meridians and magnetic meridians which vary by geographic location on the earth. On the other hand deviation is what affects only a magnetic compass by metal, electrical current, nylon clothing creating static electricity as well a numerous other effects..... etc.
Only a very expensive gyro compass will not have nor demonstrate deviation.
