how to stop showing completed parts of journey on map

[SimonC]

Hi everyone.

I have an XT, which I love. The only thing that irritates me is that is continually shows the entire planned route throughout the whole journey.

My normal use process would be:

• Start from 'Where to'
  Set several stops
  Follow the map.

I want to set it so that it erases the route behind me as I travel; leaving the screen less cluttered (just like it does in a car.) The main reason for this is that a local, multi-stop journey (for example) can end up with intersecting route lines. This can make it messy and confusing on screen. I tend to use the map rather than turn by turn directions.

Is there a way to achieve this continuous removal of 'expired' parts of the journey?

I hope I've described this OK. Look forward to your replies.

I agree with wishing the route line behind me would always disappear. I have seen it disappear, but have never determined what triggers it to do so.

[SimonC]

Ah, that's promising. At least it sounds possible, if you've seen it happen.

[Peobody]

I've been thinking about this and two conditions come to mind. The first is obvious, which is following the restart of a route in progress. The second is after visiting a via point. I now use mostly non-alerting shaping points but a one time I used only via points to shape my routes so I'm wondering if that is what I am recalling. You may know the answer if you use via points. If not, feedback from others is needed.

[SimonC]

I only use it as a basic nav unit. If I understand you correctly, a via point would be a marked 'stop' en route? I.e. you go via location x, y , z etc. You propose that once location x is reached, the track leading to it disappears. Would that be right? I'll have to try this and pay attention to whether it does that. This is my normal way of setting up a route but I've not noticed this behaviour. I'll try it this weekend.

I don't think I've used shaping points yet.

I was thinking more of a way to get the trail to literally erase as you pass along it.

[Peobody]

I rarely use my XT as a basic nav unit. I want to control the roads on which a route will traverse so I create routes in Basecamp and then transfer them to the XT.

I was thinking more of a way to get the trail to literally erase as you pass along it.

I am pretty certain there isn't a way to do that.

[SimonC]

That's a shame. It would be very helpful for urban use.

Thanks for replying though

BTW, I've looked up the shaping waypoints. Quite handy. might have a go at these for longer runs.

Is this the sort of thing that you are trying to do ?



(Watch the video to the end)

Note that the route recalculates when I ignore the 2nd exit from the roundabout and take the third. The route behind me is them removed.

But when I miss the turn for the later shaping point, I am immediately back onto the magenta line and it doesn't recalculate - so the route behind is not removed.

I came across it when I was doing some pretty thorough testing for the RUT behaviour on the XT1, and thought - that's interesting - but I haven't actually come to any conclusions about exactly what triggers it and when it happens.

I've had a look throught he videos I took during that busy two days, filming the XT1 and deliberately missing route points. But although I can see it happening - there isn't enough evidence to pin it down.

But this is what I think - and it is probably closer to the truth than I am prepared to admit.

1. You need a 'Saved' route (ie created on the XT1 itself) OR an imported route (gpx) that has been tweaked so that the Zumo thinks that it is saved. Link about that to be added here.
2. You need to have a route point early on in the route that you can skip. ie you put a Via point on the route (say) 2 miles from the start so that after you have passed the start point, you have enough time to pull over and skip the dummy route point.
   This causes the entire route to recalculate and it then behaves slightly differently. For imported routes it behaves like a Track-Trip (ie a Track that has been converted to a trip.
3. Thereafter, if you ignore a direction or the route has to recalculate it starts a route from where you are now, and anything of the original route that was behind you is not plotted.

All of the above is true - but whether or not you have to perform each of those steps, or there is another way to trigger this behaviour, I don't know.

1. You must make the XT think that the route is a saved one. You are about to skip a route point, and if the route is an imported gpx file, rather than a saved route, then that produces the conditions where any future deviation results in RUT behaviour. It also treats avery route point as entirely optional. You can just ignore them - go past the turning and the Zumo removes them from the screen !!
   
   Like this one:
   
   
2. This may not be necessary - but I haven't seen it remove the route behind without this being done. But this was the way that I knew that I could force RUT behaviour to happen, and since that is what I was testing, I didn't try any other methods.
3. From this - it sounds like you have to go off route to force a recalcualtion. So when planning your route, you could force a deviation by deliberately placing a Via off the route and then skipping it; place a route point on a motorway exit (so it can plot the route back onto the motorway). You then ignore it. Plot a via in a field that you cannot possibly visit. Then when riding, skip the point - the XT will prompt you.

Contrived, I know - but that is as much as I can come up with at present. You may be able to find out more for yourself.


Oh - and if you have seen this before - then your XT has been in a situation where it could develop RUT behaviour - unless the route was a 'Saved' one.

@SimonC

I've looked up the shaping waypoints.

Shaping points, waypoints and via points are 3 different things although many use the terms interchangeably, which adds to the confusion.
I mean no offense - I'm just on a bit of a mission to clarify the terms around GPS.
There are also track points and points of interest.

In case it helps you, there is an explanation here https://www.zumouserforums.co.uk/viewto ... 308#p22308

That testing took quite some time, but it really paid off! We learned a lot that we weren't looking for at the time, but comes in handy every now and then
