Why does route change when connecting to Android Auto?

[Brian Martin]

Quite often after selecting a route on my Android phone then connecting to Android Auto the route changes. After carefully designing a route on my pc and syncing it to my phone and after connecting to Android Auto and Start navigation, I find part of the route sometimes gets changed. It's most frustrating as I have to keep checking the map before I start navigation to make sure my original route hasn't been altered. Anyone else have this happen?

@Brian-Martin In principle, Android Auto is a mirror of your phone, and AA will not change a route on its own. Any route changes would also occur on your phone as soon as you tap Navigate.

Could it be that you created the route using a different map than the HERE map (for example, OSM or TomTom)? Are any road closures visible on the map along the route you created? Which area does the route pass through? Is there a seasonal road closure involved?

It might be helpful to share your route in this topic so others can take a look.

Not especially altered. But when connecting to Android Auto after starting a route on the smartphone. MRA seems to do a sort of refresh. This does things with the route. You see things happens on your phone screen.

That can only be the case when selecting a A B route. A route from your librairy doesn't change

@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.

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).
