204 Zumo XT - RUT Behaviour - Ignore Via Point - Imported Route
The Video
The route is part of the same locatuon as the previous test for a 'Saved' Route. This route however is 'Imported' - it has been created using mapping software. It has a start point and end point and some Via and Shaping points.
In certain circumstances (described in 'My Input') these imported routes will behave very differently - as you shall see.
Watch and Listen
I am just driving and letting the satnav do its thing. The satnav is in a home made mount on the passenger seat of my car. However, earlier in the route I had a Via Point, placed there on the road I was travelling anyway soon after the start. Its only purpose was so that I could Skip the route point. I started the route, pulled off the road before the Via and pressed the Skip button.
This is a surefire way of triggering RUT behaviour if I deviate from the route at any time in the future. After pressing Skip, the entire route is recalculated between - but still passing the route points. RUT behaviour has been observed in other circumstances - but skipping and later deviating form the route nearly always triggers it.
I did the same thing with the Saved route - just to make the tests the same.
Conclusion
I'm not sure that this is what I want - I am torn between two points of view.
Watch and Listen
- The change in brightness of the magenta line. The route as a whole is a dull magenta colour. But the section of the route that I am currently following is much brighter. You can see the difference as I approach the flag.
- The on the distance values in the Trip data display on the right.
- The route behind disappears once I have gone past the Via point and the route has recalculated.

- If I have a Via points, then it is a stopping place - eg a location for my lunch break. This suggests that in certain circumsatnces, the XT will remove my mid morning break from the route - if I cannot get to it - due to roadworks perhaps.
- If I have deliberately not followed the instructions to visit a Via, then I clearly have no intention of going to it. Therefore get rid of it.
