So far, after two days, I can't complain. This AM, I ran the GPS for over two hours walking the dogs at 3-5AM, got onto a phone conversation that started when I was walking using earbuds, very smoothly switched to the Truck's BT connection drove 100 miles to Pocatello and I know in some of those areas it switched out of HD mode (LTE) since it didn't exist. Then in the way home, got into another phone conversation. Surfed the net for about a half hour, and still at 79 percent. Good or bad, it is working OK for me, and pretty sure it will get better with usage.
