Android Auto and Caplay activation

[Dougray]

It works without the USB hub. 

Did you get the button on your screen? 

The 362 option is just part of your build list and change isn’t required for AA/ACP.

Can confirm this. I enabled Android Auto and Apple Car Play (smartphone integration) today without upgrading to the double USB hub, just the standard single socket. I use Android and it works great, aside from the stupid Volvo sensus system only using the bottom half of the screen (might eventually buy the Isudar system to overcome this). Using a fairly short, mid range cable from Amazon, nothing special. Following config changes used.

I actually bought a double USB hub to fit, assuming this was required for the upgrade, so may still install it, but definitely not necessary.
