This is interesting. Android Auto is bound to Google even on Graphene? That's alarming.
I am old-school man, having a holder for a phone and using navigation on the phone.
Isn't that still better option to being Google dependant?

Which phone navigation are you using?
Depends. Most of the time Wase (is separate umgoogled sandbox). The data on police patrols is unbeaten. But the privacy downside it's obvious (it's owned by Google). Sometimes OsmAnd~ when I need to be not-watched / offline or when I am in the urban/remote areas where knowing detailed cartographic data is more important then traffic/police warnings.
