I was have problems with switching between my wife's iphone and mine. I was having to do a reset of the network or a hard reboot of the box.
I have a PX6 with Andriod 10 (latest). It seems to remember the last phone when you turn off the car. So, if my wife getting into the car (and I used the car previously). She has to go into bluetooth and press on my phone entry. It would says "Would you like to disconnect? Press YES". Then she would have to press on her entry and get "Would you like to connect? Press YES". Then there would be a few issues. But, carplay would start working. I just thought I would share.
