37 Ignore a Route Point

  Contents First Previous Next Chapter

What happens when you miss a route point.


By ‘Ignoring a Route Point’, I mean that when driving or riding along, the Zumo is telling you to take a particular turning and you decide not to go that way, for whatever reason.  No matter what type of point the XT is trying to take you to (Shaping or Via), the Zumo’s behaviour is predictable, but it depends upon the settings that you have selected for Settings -> Navigation -> Off-Route Recalculation.
 


In any situation, the Skip button will stop the Zumo navigating to the next routing point, and head for the following one.


If Off-Route Recalculation is set to Automatic:


The Zumo will automatically recalculate a new route. To do this, it uses the remaining route points and the Zumo’s routing preferences ** for the route’s vehicle. There is no announcement and the route that the Zumo had been following for that section will be replaced by this new route. Unlike some earlier Zumos, the XT will re-calculate every section of the route when Skip is pressed, not just the current section.

If Off-Route Recalculation is Turned Off:


The Zumo will do nothing if you go off route. The plotted magenta route will still be visible if you zoom out far enough, but no attempt is made to re-direct you to any point that is on the route that you were following.


If you navigate your own way towards the magenta route, then as soon as you intersect it, the Zumo will begin navigation again, but where it takes you when you rejoin the route will depend on whether or not you missed a Via Point and are now on the route after that Point.
  • If you have missed a Via Point, the Zumo will give you instructions to get you back to that point.
  • The XT will try twice to get you to go back to the missed Via Point (or Shaping Point). After that it displays a message asking if you wish to Skip the point (and gives you the name of the point).
  • If you have not missed a Via Point, then the Zumo will navigate you in the correct direction to the next route point - it doesn’t care about missed Shaping Points if you are back on the magenta route.

If Off-Route Recalculation is Set to ‘Prompted’


This is probably the best option to select until you get to know what the Zumo is doing. A message will appear on the screen and ask you if you want it to recalculate - (ie the route from your present off route to the next route point (Shaping or Via). If you say ‘Yes’, it uses the Zumo’s Stored Routing Preferences to recalculate a route.

If Recalculation is turned off, or you select ‘No’ when Prompted to Recalculate


Basically, you’re on your own. Once you rejoin the route the satnav will try to take you from there, or it might take you back to a Via Point that you have missed. The problem is that you may not know. There are ways out of this: Re-start the route and when asked for the next destination, select a Via Point that you know to be ahead, or better still, select Closest Entry Point. (Make sure that you allow U-turns).


If you continue navigating instead, then the Skip button becomes quite useful. It gives the name of the route point that it is trying to take you to. Also if you ignore the instruction to go back twice, it throws up a prompt on the screen, asking if you want to skip the route point that it is trying to take you to.


But the best solution is not to end up in this situation in the first place. Shaping points are quite forgiving in such situations, not so Via Points. But Via Point are useful for major stops.


Suggestion. Use Via Points to separate the stages of a trip - placed at or after the main stopping places. Use Shaping Points to force the route onto particular roads - but use them sparingly. Well away from junctions is usually better.


It helps if Via Points are sensibly named so that you can work out where they are in relation to where you are. For unknown areas, once a route is finished, I add a 3 digit figure to the front of the name to represent the mileage from the start of the trip. I can then compare this with the bike’s trip meter.


nb Only Waypoints (created with the Flag Tool in Basecamp) can be guaranteed to retain their name in the XT (v6.30)

** Routing Preferences.


By this I mean the settings that the Zumo uses if it has to re-calculate its route.


The Vehicle (eg motorcycle) and the Routing Preferences (eg Faster Time) both come from the Trip that was sent from Basecamp - not the current XT settings.
If these aren’t specified in the Trip or the GPX file, or are not recognised by the XT, then MotorCycle and Faster Time are used.


The XT does not use any of the other settings that might have been set in the Basecamp Profile - eg avoidances. It can’t. Basecamp does not send that information to the Zumos.
