For anybody that is still experiencing this issue, I ordered a new media hub… And installed it, and still had the same issue… Constant power cycling off and on, and no CarPlay connectivity. After troubleshooting, the media harnesses back-and-forth between the two media hubs I have, I noticed that unplugging the right connector sent constant power to the USB, as before it was installed, I could see the lights constantly on. So what I did is continue to troubleshoot, and just before giving up, I went underneath the console, lifted it up, and unplugged a harness underneath. Instantaneously CarPlay turned on, I had my phone plugged into USB at the time. I was in disbelief, didn’t know if I wanted to try to plug back in that harness underneath, so what I did is I tested the USB in the back and they all worked. The 110 power in the back also worked. So, with some hesitation, I plugged in that harness underneath the console back in, and everything continued to work. I reinstalled the center console, and as of right now I have CarPlay. hopefully this helps somebody out
