I did get it working after joining the Google beta program.
When it's on its nice.
Quite a few issues.
Won't auto re-pair with my phone when I get in my truck. My outlets are always on and I need to power cycle the roav for it to re-connect.
Doesn't listen to voice commands. It hears hey Google lights up and doesn't seem to comprehend anything.
Laggy. When it does come on from hey Google it has a serious lag until it responds and the lights turn white. Judy for it to time out while I'm repeatedly asking for what I need.
Meanwhile my wife's phone in her pocket on the far side of the truck starts doing.
