A direct answer to your question.
No. Probably not. But maybe.
I've altered the descriptionbelow since I first posted this reply - as hopefully it will make more sense to anyone coming across this discussion and wanting to know what RUT is.
RUT is not a widely recognised term. It something that I came up with when I first started to understand the XT's weird routing behaviour. If I had to leave a route (either forced or by choice), often it would repeatedly demand that I go back to that point of deviation - rather attempt to take me to the next route point ahead.
Now Repeated U Turn requests are not a fault. You can get them quite legitimately in the following situations
- Missed Via Points (no escape from those)
- Missed Shaping Points (There is an escape from this situation)
- Misplaced route points (commonly - route point on wrong side of dual crarriageway, in a field, rather than on a road, .....)
- Via and shaping points - behave differently and can confuse.
- Failing to pass through the start point of a route.
These sitautions do not hint at RUT behaviour. I know, because I defined the term.
They are often simply user error / user misunderstanding - and we have all been there !!
RUT behaviour shows itself partly by repeatedly asking you to go back (apparently to the point of deviation from the route -either by U-Turn requests or by using side roads, crescents etc to turn you around. But RUT also shows other charactersitics and behaviours which help us to identify it correctly. Mostly I cannot tell whether the XT is displaying RUT behaviour or whether I have messed up with my route points - I need to gather the evidence.
But I have done that. So have some other members on the forum. And once I was able to describe exactly how to make it happen and the circumstances when it would never happen we have three different methods of stopping it from happening on any route.
----------------------
But the question - Is this RUT ? is a refreshing one to see. Recognising that you have odd behaviour and not wanting to blame it on an acronym that I wish I had kept to myself !
So To address your ice cream stop issue: It depends what route point you placed at your ice cream stop.
If the ice cream stop was placed as a via point (orange flag) then the Zumo treats it as a Must Visit point. It will keep trying to take you back. Forever.
If the ice cream shop was placed as a Shaping Point (blue disc) it will still try to take you back to it until you visit the point OR you rejoin the magenta line after the shaping point.
In your situation it sounds like you plotted the same road back from the ice cream place - so if the ice cream shop was a shaping point, when you ignored the turn, you would immediately be on the next section of the magenta line. The Zumo wouldn't have missed a beat and would not try to make you visit it.
So I guess that you plotted a Via Point - in which case, what you describe is normal behaviour. You have to visit a Via Point.
Unless you happened to have skipped an earlier route point - in which case subsequent deviation from the route will likely develop RUT behaviour - always, in my experience.
----------------------------
The Zumo can have two types of route point:
- Via points which are shown on the map as an orange flag.
- Shaping points which are shown as a small blue disc on the map
On the Zumo, Via Points are sometimes referred to as 'Destination' or 'Stops'
In Basecamp, you can view a list of all of your route points in order, by double clicking the route name, or the coloured route on the map.
In that route list you can reorder the route points, or click on each point in turn to highlight the location of the point on the map. This is particularly useful if you select the tick box at the bottom that says something like 'Center Map'' - as when you select a point, the map zooms in so that you can check the accurate placement of each point.
This is made even easier if you select the top point and then use the cursor keys to move down and up the list. You can also untick the box which controls the amount of detail in the route list 'More Info' - so that you can see more of the map behind.
Right click (PC version) on any route point in the list. A pop-up menu offers all sorts of options - one if which offers either 'Alert on Arrival' or 'Does not alert on Arrival (shaping point)'. You can toggle between the two states.
It is this that determines whether the route point is a Via Point or a Shaping Point.
In the list itself, you can recognise the type of point.
Via points are shown in black text.
Shaping points are in grey text and have '(won't alert)' added.
-----------------------
When planning a route aim to have just a few Via Points eg to mark stopping places - places that you will definitely visit. Use shaping points to pin the route to particular roads. If you have an optional stopping place, mark it with a shaping point perhaps with a Via Point just before (so that the Zumo alerts you (Arriving at Ice Cream turning on the left) or just after - on the road you will take whether or not you will have an ice cream - which makes it easier should you need to restart the route.
Chapters 1 & 2 in the link below cover most of this. Chapter 2 covers what I have summarised about via/shaping points with illustrations. Chapter 1 covers the types if route point.

Both of these chapters apply to the XT2
This link BELOW describes RUT behaviour observed, proved and solved for the XT.
So far I have been unable to make my XT2 display this behaviour. Yes it will ask for u turns, but generally these are legitimate requests to get to the next route point faster.

==================================================
nb If none of the above applies to your situation, then I am intrigued and would like to know more detail. I have been trying to make my XT2 to display RUT behaviour, and so far I have failed.
Early days, but it seems that my years of providing evidence have been listened to - but a solution has not yet appeared on the XT.
