Pretty sure the USB port is just broken. I also tried with an Android phone and same result. Putting in a USB thumb drive with music on it results in the USB option is source being greyed out and unable to select. When I plug a phone in, power is sent to charge the phone, and the light on the USB drive flashes once when inserted but no devices are recognized. I suppose the data pins in the port are compromised but not the power part. Still under warranty so hopefully they can just pop a new port in there; I think it's a removable part.

Mine has failed twice now. I use Android Auto, but the symptoms are the same: USB port charges, but won't make a data connection.

After the first failure, the dealer was instructed by GM to test the port and the wiring, but ultimately ended up replacing the head unit. Problem solved for a little over a month.

I'm kind of happy to find that I'm not the only one. I was starting to get paranoid that I was doing something to cause it.

check if there is something stuck inside the USB port that prevents it from communicating properly with your smatphones.

Yeah they just put a whole new head unit in mine too. I really don't care about the Carplay part, I mostly just need the USB port for my music which now works!
