37Setup PageThe eTrex bearings will correspond to a compass if the eTrex is set to magnetic north.Due to errors introduced when map makers flatten the earth’s sphere onto paper, not all ofthe grid lines drawn on the map point exactly to the north pole, so the north indicated bythe grid lines is called ‘Grid North’ (GRID). But, the difference is usually small enough that‘Grid’ north can be considered the same as True North for travelling on land.
