This has been my experience as well. I’ve been using it on my Honda since 2015, and have not had any problems except 2. Once it was just an old USB cable that needed to be replaced. The other issue was sometimes the Bluetooth doesn’t connect the right way so I have to turn off Bluetooth on my phone then connect the USB to my phone which forces it to connect correctly. The Bluetooth issue was recurring (once every month or two), but hasn’t happened for nearly a year now.
Pretty sure there’s an android auto API for music apps and stuff (that’s why Spotify and pocket casts and many audiobook players support it), but unfortunately there aren’t non-Google navigation apps (unsure if that’s because Google won’t allow them or because there just aren’t any).
Oh that’s cool! Is this local for the Czech Republic? How does it compare to Google maps/navigation?
