External references are signs or waypoints where we don't know the measurement until we get there, but we know in advance the passing time or the average speed that we will change when passing by. In order to identify this point, in the roadbook you will have a photo or some other information that will allow you to identify this reference, so you can discover its mileage during this stage. Let's see how this works in Rabbit.
6. If necessary, repeat the same for all external references of the stage.
7. Now just enter the start time, send to the navigator and wait for your start time.
3. The Rabbit will do the calculations for you and you can proceed to the next waypoint by repeating the previous steps with the yellow bar.
Note: If you use the Rabbit Box, the yellow button serves to confirm the reference point (same as the OK button) without needing to touch the screen.
