Received the CarPlay2Air yesterday, and it worked right out of the box. I undated the firmware, after that it would not connect to my 2017 LTZ. I followed the instructions to totally disconnect it and then reconnected it, that did not seem to help. I tried that again (did not seem to work) and then went for a drive. After a few minutes the carplay button came on, but I could not run carplay, hitting the button did nothing. I power-cycled the media player, and hit the carplay button again. Carplay launched via CarPlay2Air and it just worked. Worked for the rest of the day. It does take some time to connect (up to 20 sec) when I leave and return to the truck. We will see how it works today.
