I would like to control few functions while driving.
navigation (osmand), play music (multiple apps) are main ones.
As of now I think either voice assistant or car UI are 2 options.
So are there any apps supporting these?
if I understand correctly there is no way to make FOSS AA (protocol itself is not open unless reverse engineered).
There needs to be separate implementation like AA / CarPlay and headunit needs to support it.
Current best case scenario is miracast supporting headunits (but this is one directional)
