I don't understand this insanity stuff. We have a $35 chinese brand (Ugreen FWIW) bluetooth adapter in our car. If it connects to my wife's phone when I go start the car (or opposite), all I have to do on Android is to pull down the notification drawer, long-press the bluetooth icon to open the bluetooth settings, then click the name of the desired device in the list that comes up. 10 seconds later it has connected correctly. This $35 dongle also has pause/play and skip buttons, and you can use those to answer calls as well. The buttons are tactile so you can use them without looking. Honestly, the only bad thing is the built-in microphone delivers pretty bad audio when you use it as a hands free. But for $35 I cannot complain.
