I'm sure you've realized your dream phone will never exist, it sounds more like an older ultrabook than a phone. What's the reason for a USB port, much less two of them? Every new vehicle the past few years has bluetooth, so why a loud speaker?
I'm well aware that the dream phone may never exist. That doesn't mean I don't want it.
I fixed it by replacing the head unit with one that supports Bluetooth and CarPlay. An easy DIY project or you can pay a small fee to have it done for you by an installer.
I don't know if it is possible for the phone to provide this, but it is on my want list.
Two USB sockets is like two SIMs. It sounds crazy to most people who’ve never had them, but for a lot of other people they are / would be amazingly useful.
