Heya,
I’m trying to go through Europe in Co-Maps. Particularly, I want to use offline maps to avoid aggressive roaming fees during one part of my route, as well as have a robust backup if online maps breaks. This seems to work great in preparation so far.
One thing I’d like to account for, is that driving through Switzerland is very expensive. I would rather want to detour slithly south through Austria, but I can’t find a good way to communicate that to the app. I could try with some intermediary stops, but that seems like it would muddy the routing algorithm even more.
Is there a way to prefer/avoid areas or countries? Or a way to prepare a fitting route externally in advance, then reliably have it work in the app?
Thanks in advance.


Just download all the maps beforehand and stay offline. Also there are no roaming costs EU wide anymore.
That is no answer to the original post
Also, Switzerland is not EU
In respect to this issue it is. There is no roaming cost in Switzerland either. The Swiss pick and choose freely what they share in the EU laws.
Are EU operators forced to provide a free roaming to Switzerland tho? I guess that’d be the question.
