In classic navigation at the beginning of the journey we need to know where we are in order to plot where we are going. If you navigate with a compass you need a map to show you where you are and where you want to go. This then gives you a bearing and distance.
With innate navigation you do not seem to need to know where you are in order to decide where you are going.
Homing pigeons spiral into the air as they are released and then set off in the approximate bearing for their lofts.
There are many birds, animals and fish that seem to sense the direction that they must travel and set off in the right direction.
The analogy is perhaps picking up a GPS device and tapping in your destination. You do not need to know your location but the bearing you need is there.
There seems to be no requirement for knowing where you are to trigger a sense of the direction you need to get to your destination.
