I was wondering if a (slightly) older phone could be wired in through USB and running Android auto, but connect to the internet using a wifi connection to my current 4G cell phone (which can broadcast a wifi hotspot). This way, I could run Waze, PocketCasts, etc. without having to get my phone out and physically plug it in each time. But I'd probably have to turn on the second phone each time, which would only be slightly less trouble. Or I could just wait it out until they allow non-Pixel phones to connect to AA via wifi...
