Truck went back in yesterday. Dealer calls and says that they called GM and apparently it is a known issue with the latest infotainment update (phone won't even be recognized when plugged in), but google is working on a fix, so basically nothing i can do. Wait, theres a problem with your last update making Android Auto completely non-usable, bit Google is working on a fix??? right. Anyway i just walk away and figure I will try another dealer and see if this is a load of BS or not. I get in my truck and my cell battery is low so i plug it in. AA works fine???? Anyway I'm back to where i started Android Auto at least works, but I still get no text notifications. I will try a different phone and see if i can not isolate the issue to my phone or the truck now
