Why does route change when connecting to Android Auto?

[Herman Veldhuizen]

Using here maps only is no guarantee that the navigation comes with the same route as what you crafted in the planner. At least that is what I have observed. Dont know where the problem is. Could it be that planner and navigation are not using the same user settings? Differences between the routing engine in the app and on the server?

@Herman-Veldhuizen Or maybe you should use more route points at critical locations! I use as few as possible, but as many as necessary...

No, theoretically not, since the avoidance settings in the planner replicate to the app along with the route. There can be differences in map-versions though, and also of course in trafic information.

Als ik de knop start indruk van de route dan verschijnt er een popup schermpje met de tekst; 'TomTom route Track navigatie gebruiken'
Wat betekend dit???

Please try to adhere to the language in the opening topic.
The message indicates that the route was planned on the TomTom map, and therefore will be navigated as a track instead of a route.

[Herman Veldhuizen]

@Con-Hennekens There are more settings. The functional navigation settings in the profile.
What I observe is that when I navigate a route as track, a closure can be ignored, but only when I navigate from the opening page of the route. When I navigate from the in-app route editor the closure is not ignored.
In areas with few roads, like here in Norway, a closure of a road can have a big impact. So what the app navigation comes up with can be very different to what you crafted in the in app editor, all with the same type of maps.

@Herman-Veldhuizen, I was merely referring to @atse-kroes addition.
To answer your comment, I think when you open a route in the app-planner, and the detour is already shown there, that becomes the new "original calculation" of the route.

[Herman Veldhuizen]

@Con-Hennekens not sure what you mean, but all what I am after is consistency. Ignoring closures might be the right thing to do but then i would like to see the same in the in-app route editor, without having to sprinkle my route with waypoints which don't represent anything and without having to change some settings between editing and navigating. The in-app editor is the only editor I ever use.

The images below illustrate the issue.

The first one shows my mini test route in the editor.
The 2nd and 3rd show what I can see during navigation (route as track). Sometimes the 2nd, sometimes the 3rd.

@Herman-Veldhuizen, Thanks for clarification. Do I understand correctly that one is opened direfrom the route menu, and the other from the in-app planner? Interesting...

[Herman Veldhuizen]

@Con-Hennekens correct.
The first one (2nd picture) from the opening page of the route (select route, navigate).
The second one (3rd picture) from the in-app editor (select route, edit, navigate).
Corjan had a look at it but I am not sure what the conclusion was.
I dont often start the navigation from the editor but in this case it would actually best match what I see during planning.

[Con Hennekens]

@Herman-Veldhuizen, I must say I do not use the in-app planner a lot, so I never noticed this difference. I am afraid I cannot add much to this if Corjan is already looking at it...

@Con-Hennekens if you want to try it :

[Con Hennekens]

@Herman-Veldhuizen, actually I am getting the same detour in both cases...

[Herman Veldhuizen]

@Con-Hennekens so do i if i navigate as route. if i navigate as track i get 2 versions

[Con Hennekens]

@Herman-Veldhuizen, ah yes, I see what you mean. But actually I find that rather logical. "Navigate route as track" only kicks in when you start navigating. By opening the route (it's not a track!) in the planner, the route already changes to create the detour. Then you start navigating that changed route as track, so it includes the detour. When you do NOT open it in the planner first, you navigate the unchanged route as a track, and you know a track won't change due to traffic. So I can imagine that Corjan's conclusion was: "it's by design"
