new ford F350 with Android auto, One plus 5.. google assistance has worked whether USB plugged in or not. 'OK Google' brought up the floating dots and listening beep..
both on phone and AA

starting this week, after some phone update, see GA was updated on mar 5.
v 0.1.187945513,
as soon as I plug in USB to car device, , voice reco of 'OK Google' is gone.. and I must push the voice button on my steering wheel.. if I unplug the usb cord, then phone 'OK Google' is active again

is this how it will be going forward? 'hands free' really isn't if you have to push a button

Google is changing how Assistant works. Apparently it now will not unlock a device when triggered with a trusted voice, I have to wonder if this was another unadvertised change. For what it's worth - my Pixel 2 XL still responds to the command when AA is on the screen (I don't have it on my car radio, just using it stand-alone for now), for now...
