Why does route change when connecting to Android Auto?

@m.-schrijver
Did you placed enough waypoints? And what are the settings in your MRA app?
And as @rob-verhoeff said, please share the route and provide more info.

[M. Schrijver]

waypoints are not the issue. In my case the routes are not altered but when connecting to Android Auto i see things happening on the screen of the phone. It looks like MRA is bit confused whats going on.

Could it be that there is a closed road on your route? Then the route could indeed be different than what you see in the planner and it is indeed very frustrating when you have used the HERE maps only and when timing is not the issue (navigating straight after editing).

Ik heb hetzelfde probleem. Ik lees elders dat je beter Here map kunt gebruiken. Ik heb TOTOM map gebruikt. Is het waar dat ik dus beter Here map moet gebruiken voor in de auto met MRA app te reizen?

Ja. De navigatie werkt altijd met de Here map. Dus als je een route maakt met een andere kaart als laatste de route op de Here-kaart leggen en controleren.

Yes. The navigation system always uses the Here map. So if you plan a route using a different map, make sure to finalize the route on the Here map and check it.

Thanks for the replies. I do use the here maps and I use MRA in offline mode. I shall keep monitoring the situation to see if it keeps happening. I have an existing route planned for tomorrow, so I'll see if it behaves itself or not.

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???

[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?

[Rob Verhoeff]

@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.

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.
