i.e. it's not about being a fan of particular brands, it's a self-interested desire for a decent UX/platform.
Apple/Google are not a nice experience. If you could share your screen would have been ok. But running special apps is out of discussion. I tried Android Auto. It is terrible, it needs a lot of time to set up (permissions, settings on car), the car must be stopped (ignition off) and 95 % of apps installed are not compatible. In the end, to listen music i have memory sticks and for navigation a Garmin.
First time plugging in, a simple confirmation on my phone to allow connection. CarPlay starts, everything works out of the box. Now I can phone, can search my music library (try that with bluetooth) and I have a voice control that mostly understands what I want to play.
